Abstract:
Horizontal impact tests of stainless steel–reinforced concrete piers with different reinforcement ratios at different impact velocities were carried out by using the ultra-high drop weight impact test system. Degree of piers damage after impact was comprehensively analyzed by measuring the acceleration of the impact body, the displacement of the top of the pier specimens, the strain of the steel bars, the rotation of the pier bottom, and the crack development of concrete. The test results showed that under the same impact velocity, with the decrease in reinforcement ratio, the peak acceleration of the impact body, the displacement of the top of pier specimens, the strain of steel bars, and the pier bottom rotation all increase. To a certain extent, increasing the reinforcement ratio of bridge piers can effectively reduce impact damage.

Abstract:
Piers can be severely damaged by earthquakes. When an action of a massive earthquake is assumed, the seismic performance of the pier can be improved by widening the foundation width. A previous horizontal loading study indicated that extending only the Foundation Bottom (FB) width, rather than the complete foundation, can boost seismic resilience while suppressing the increase in building cost. However, the research dealt with only two types of FB width, i.e. normal and widened, and the data for sufficiently assessing the inclination angle of the pier with loading were not obtained. In this study, to evaluate the seismic performance of piers with different FB widths in more detail, horizontal loading tests on piers with ordinary columnar foundations and two types of piers with widened FB were conducted, and the seismic resistance of the three pier types were compared. It was shown that horizontal displacement and inclination angle of the pier can be reduced by widening the FB. Furthermore, finite element analysis was carried out to reproduce the experimental results. The analysis results showed good agreement with the experimental results in terms of pier horizontal displacement and inclination angle.

Abstract:
Initial damage often exists in the concrete piers of bridges in service. In this paper numerical analysis was used to study the seismic strengthening behavior of concrete bridge piers with different bending damage degrees, including seismic forces, pier top displacements, steel bar strain and energy dissipation, in order to obtain the strengthening demand to repair the damage piers. The results showing that: initial bending damage reduced the seismic force, increased the pier top displacements and the steel bar strain. After strengthening the pier top displacements and steel bar strain at the pier bottom decreased, energy dissipation increased, and the anti-seismic properties of damage piers effectively recovered, but the increase of the seismic force might make new plastic-hinges out the strengthened area. At last according to the mechanics properties the strengthening demand under different bending damage degrees was given.

Abstract:
To investigate the static performance of precast segmental hollow piers, two precast segmental hollow pier specimens were designed for static loading tests on the top of piers. The finite element model of precast segmental hollow piers was established by the finite element software Abaqus and verified based on the test results. Based on the experimental and finite element models, three optimal design solutions were proposed, and the calculation results of each solution were analyzed. The results show that precast segmental hollow pier mechanical behavior is similar to that of cantilevered bending members. The specimens present brittle damage characteristics after the destruction of the structure at the bottom of the pier pressure edge as the axis of the rigid body rotation. Following the test loading process, the bonding between the segments is good, except for the pier bottom damage surface of the rest of the bonding surface, which has no relative displacement. The calculation results of the finite element model are in good agreement with the test results and can effectively predict the load–displacement response of precast piers. Three optimized design solutions are proposed. The finite element simulation proves all three optimized design solutions show better overall ductility than the original solution and can effectively improve the performance of segmental precast hollow piers.

Abstract:
Crest piers placed on overflow spillways induce standing waves at the downstream end of them and the supercritical flow expands after flowing past the rear of the pier. The expanding flow from each side of a pier will intersect and form disturbances or shock waves that travel laterally as they move downstream and eventually reach the chute sidewalls. Recently, investigations regarding crest piers are related with artificial aeration on stepped spillways to eliminate the risk of cavitation damage. However, there is a lack of studies on standing and shock waves in smooth spillways concerning the air entrainment into the flow in presence of crest piers. This paper presents the study of the combined effect on air entrainment of a crest pier and an aerator on the bottom of a smooth spillway (configuration 1). For comparison, experimental tests were developed in the spillway without pier, that is in presence of aerator only (configuration 2). The configuration 1 results show that the air concentration distribution on the spillway bottom across the width and length of the chute increases in comparison with configuration 2, reducing even more the risk of cavitation damage and enhancing the safety of the hydraulic structure.

Abstract:
At present, research on prefabricated piers is limited to the axial compression state. However, many piers are under small eccentric compression in practical engineering. In this article, the seismic performance of ultrahigh performance concrete (UHPC)-grouted corrugated pipe-connected piers under small eccentric compression was studied. A pseudostatic test was carried out by using a prefabricated pier column model connected with UHPC-grouted corrugated pipes. The failure mechanism of the plastic hinge area of the column base was studied, and the failure mode, energy dissipation capacity, displacement ductility, and ultimate bearing capacity were compared with those of an ordinary axially compressed pier column structure. The result shows that compared to the conventional cast-in-place(CIP) pier, the overall energy dissipation capacity and the ductility factor of assembled pier with UHPC-grouted corrugated pipe-connection were decreased approximately by 5.0% and by 10%, respectively. The pinching phenomenon of the hysteresis curve of the precast pier was more obvious. When the assembled piers were under small eccentric compression, the overall energy dissipation capacity was close to that of conventional CIP piers and the ductility factor was improved by 20%. Comparison of two precast piers using the same UHPC grout connections shows that the stiffness degradation process of precast pier under small eccentric compression was similar to that under axial compression. But the ductility coefficient of precast pier under small eccentric compression increased by about 20%. The small eccentric compression caused different damage degrees in the plastic hinge zone at the bottom of the precast column. The ultimate load in the same direction as the additional bending moment was 55% lower than that of the opposite direction.

Abstract:
The seismic response of 4-span continuous bridges with different configurations has been investigated. In the series of bridges studied, the height of the central pier varies from 5 m to 100 m, while the heights of all the other piers remain the same. Using non-linear time history analysis, the internal forces at the bottom of individual piers have been predicted for each case. The correlation between the relative stiffness of adjacent piers and the ratio between the seismic response at the bottom of adjacent piers has been studied. Based on the results, in order to guarantee approximately balanced seismic response among all piers of a given bridge, a range of the relative column stiffness of two adjacent piers has been proposed.

Abstract:
Based on the finite element program SAP2000, 120 models of eight different piers with different lead-rubber bearings (LRB) are established. The seismic response analyses of piers isolated by LRB in axial direction of the bridge are carried out under the excitations of seven earthquake waves. The calculations of seismic responses of the piers with and without isolation are implemented by using dynamic time-history analysis method, and the comparison of the results is given out. Considering the isolation ratio of the moment at the bottom of pier as observation samples, the variances of the three LRB mechanical parameters are analyzed. Furthermore, the ability of the parameters of LRB to adjust the seismic response of different piers is discussed. The analysis results show that all the mechanical parameters of LRB have significant effect on the isolation ratio of the moment at the bottom of pier, and the parameters of LRB can adjust the seismic forces of the isolated piers whose height difference is less than 30 meters to be almost equal. This paper provides some valuable references for the further study of isolation design for railway bridges.

Abstract:
Taking a typical cylindrical solid pier as example, this paper utilizes the way of additional mass to consider the influences of hydrodynamic pressure on piers. It establishes dynamic response comparative analysis of single pier model under different earthquakes’ motivation taking ANSYS finite element software as computing platform. This draws conclusion that hydrodynamic pressure keeps characteristics of changing the seismic response of piers in which pier top displacement and pier bottom internal force are increased. Also it acquires the conclusion that weight and cycle of structure are related to the effect of hydrodynamic pressure. Through analyzing continuous beam bridge and continuous rigid-frame bridge, it is verified that there exists close relationship between effect of hydrodynamic pressure and inherent cycle of structure in which the higher inherent cycle becomes, the lower influence hydrodynamic pressure keeps on structure.

Abstract:
Questo lavoro fa parte di una più ampia ricerca sul rapporto tra l’Italia e i Paesi Nordici, guidata dal prof. Antonello Alici presso l'Università Politecnica delle Marche. Il lavoro è stato organizzato cronologicamente, attorno all'analisi di articoli italiani sul tema paesi nordici e di materiali d'archivio originali, tracciandone i rapporti reciproci con il pubblico italiano, e concentrandosi su viaggi ed esposizioni architettoniche e artistiche. In particolare, la ricerca si concentra sugli eventi legati alla nazione –la Svezia– che per prima ha avuto l'introduzione più rilevante nel panorama italiano, a partire dalla prima Biennale veneziana nel 1895. Il primo capitolo indaga la genesi di questo rapporto prima dell'inizio della prima guerra mondiale, grazie al contributo di persone come Vittorio Pica e Ferdinand Boberg. Il secondo capitolo affronta le conseguenze della prima guerra mondiale, con l'emigrazione del futurista Arturo Ciacelli (1883-1966), l'incisore Guido Balsamo Stella (1882-1941) ed i viaggi dell'architetto Giuseppe Broglio (1874-1956). Il terzo capitolo si concentra sui due decenni fascisti, concentrandosi sul ruolo di istituzioni come la Triennale di Milano e l'Istituto Svedese di Studi Classici a Roma. Infine, l'ultimo capitolo esamina il periodo del dopoguerra, quando l'ammirazione italiana per il design e l'architettura svedese ha trovato risonanze interessanti sia nei piani INA Casa che in alcuni progetti espositivi, nel lavoro di architetti quali Piero Bottoni (1903-1973), Piero Maria Lugli (1923-2008), Gio Ponti e Franco Albini (1905-1977). La ricerca ha evidenziato come le nuove Istituzioni, sulla scia di quelle fondate nei decenni precedenti, come l'Istituto Svedese (SI) e l'Istituto Italiano di Cultura di Stoccolma (IIC) –oggi ancora attive– abbiano avuto un ruolo fondamentale nel propaganda internazionale. Infine, la ricerca vuole mettere in luce come questa complessa combinazione di esperienze personali, riviste (di arte e architettura) e istituzioni costituisca il vero sfondo per storici come Bruno Zevi (che fu il primo a inserire tre maestri nordici nel suo pamphlet Verso un'architettura organica) e Leonardo Benevolo, che nel 1960 riconobbe il ruolo di aree ‘periferiche’ come la Svezia e la Finlandia, nella sua Storia dell'architettura moderna.
This work is part of a wider research on the relationship between Italy and the Nordic countries, headed by prof. Antonello Alici at the Università Politecnica delle Marche. The work is organized chronologically around the analysis of both Italian articles on Nordic countries and original archival materials, tracing back the mutual relationships with the Italian audience, focusing on artistic and architectural travels and exhibitions. In particular, the research focuses on the events related to the nation –Sweden– which first had the most relevant introduction into Italian Architecture since the first Venetian Biennale in 1895. The first chapter investigates the genesis of this relationship before the beginning of the First World War, thanks to the contribution of figures as Vittorio Pica and Ferdinand Boberg. The second chapter deals with the consequences occurred after the First World War, with the emigration of the futurist Arturo Ciacelli (1883-1966), the engraver Guido Balsamo Stella (1882-1941) and the travels of the architect Giuseppe Broglio (1874-1956). The third chapter concentrates on the two Fascist decades, focusing on the role of Institutions like the Triennale in Milan and the Swedish Institute of Classical Studies in Rome. Finally, the last chapter examines the Post-war period, when Italian admiration for Swedish design and architecture found interesting resonances both in the INA Casa plans as well as in some exhibition projects, in the work of Italian architects like Piero Bottoni (1903-1973), Piero Maria Lugli (1923-2008), Gio Ponti and Franco Albini (1905-1977). The research highlights how the new Institutions, on the heels of the ones founded in the previous decades, like the Swedish Institute (SI) and the Italian Institute of Culture in Stockholm (IIC) –both still active nowadays– had a fundamental role in the International propaganda. Finally, the thesis discusses how this complex combination of personal experiences, art and architectural magazines and official institutions formed the real background for an historian like Bruno Zevi, who was the first to insert three Nordic masters in his seminal pamphlet Verso un’architettura organica, and Leonardo Benevolo, who in 1960 recognized the role of ‘peripheral’ areas like Sweden and Finland, in his History of Modern Architecture.

Ferrara è tra le città con le quali Piero Bottoni (1903-1973) ha istaurato un rapporto proficuo e duraturo che gli permise di elaborare molti progetti e che fu costante lungo quasi tutta la parabola professionale dell’autore milanese. Giunto nella città estense nei primi anni Trenta, vi lavorò nei tre decenni successivi elaborando progetti che spaziavano dalla scala dell’arredamento d’interni fino a quella urbana; i diciannove progetti studiati, tutti situati all’interno del centro storico della città, hanno come tema comune la relazione tra nuova architettura e città esistente. Osservando un ampio spettro di interventi che abbracciava la progettazione sull'esistente come quella del nuovo, Bottoni propone una visione dell'architettura senza suddivisioni disciplinari intendendo il restauro e la costruzione del nuovo come parti di un processo progettuale unitario. Sullo sfondo di questa vicenda, la cultura ferrarese tra le due guerre e nel Dopoguerra si caratterizza per il continuo tentativo di rendere attuale la propria storia rinascimentale effettuando operazioni di riscoperta che con continuità, a discapito dei cambiamenti politici, contraddistinguono le esperienze culturali condotte nel corso del Novecento. Con la contemporanea presenza durante gli anni Cinquanta e Sessanta di Bottoni, Zevi, Pane, Michelucci, Piccinato, Samonà, Bassani e Ragghianti, tutti impegnati nella costruzione dell’immagine storiografica della Ferrara rinascimentale, i caratteri di questa stagione culturale si fondono con i temi centrali del dibattito architettonico italiano e con quello per la salvaguardia dei centri storici. L’analisi dell’opera ferrarese di Piero Bottoni è così l’occasione per mostrare da un lato un carattere peculiare della sua architettura e, dall’altro, di studiare un contesto cultuale provinciale al fine di mostrare i punti di contatto tra le personalità presenti a Ferrara in quegli anni, di osservarne le reciproche influenze e di distinguere gli scambi avvenuti tra i principali centri della cultura architettonica italiana e un ambito geografico solo apparentemente secondario.
Ferrara counts among the cities with which Piero Bottoni (1903-1973) has created a rich link, which allowed him to elaborate many projects and that has a constant presence all along the professional circuit of the author.

Studying a large spectre of interventions that embraces projects based upon the existent buildings as well as new projects, Bottoni proposes a vision of architecture without disciplinary sub divisions, approaching restoration and new building as parts of a unitary projecting process. Upon this background, Ferrara’s culture between the two wars and after the war is characterized by the permanent attempt to give actuality to its own renaissance history, notwithstanding the political changes. With the contemporary presence during the Fifties and Sixties of Bottoni, Zevi, Pane, Michelucci, Piccinato e Samonà, Bassani a Ragghianti, all participating to the construction of the historiographic image of the Renaissance Ferrara, the characteristics of this cultural context melt into the central subjects of the Italian architectonical debate and the debate for the defence of historical centres. The analytical study of Bottoni’s Ferrarese works becomes thus the occasion to outline, on one side, the peculiar character of his architecture and, on the other side, to study a provincial cultural context with a view to show such points of contact among the personalities present at Ferrara in those years, to observe their reciprocal influence and to distinguish the exchanges occurred among the outstanding centres of Italian architectonic culture and a geographical environment only secondary in appearance.

Abstract:
Lo studio che è stato affrontato nell’ambito del corso di Dottorato in Progettazione Architettonica e Urbana delinea, all’interno della vasta produzione architettonica e urbanistica di Piero Bottoni, i tratti peculiari che legano la ricerca dell’architetto milanese al tema del paesaggio. I progetti analizzati mostrano come il processo di modificazione dello spazio, partendo dalla coscienza dell’identità geografica dei luoghi, pervenga a relazioni dialettiche nuove tra manufatto e contesto. La prima parte di questo studio si concentra su una serie di progetti e realizzazioni nei quali il razionalista milanese pone l’accento della propria riflessione sul rapporto che intercorre tra oggetto architettonico e contesto ambientale. Le opere analizzate sono state scelte tentando di descrivere le diverse declinazioni che all’interno del progetto assume il termine paesaggio: la selezione delle opere ripercorre un arco di tempo compreso tra il 1927 e il 1959, intrecciandosi con molte delle vicende che hanno caratterizzato l’architettura italiana ed europea del ‘900. La seconda parte di questo studio analizza un’antologia di opere di Piero Bottoni in Toscana, regione nella quale Bottoni si confronta con il paesaggio della costa massese, con il tessuto urbano di Livorno, le colline fiorentine, la morfologia urbana di Siena e San Gimignano. L’analisi ha mostrato come l’architetto milanese, sebbene si identifichi come figura di primo piano dell’avanguardia europea in Italia, intraprenda fin dai primissimi progetti un approfondimento critico del Moderno. L’adesione sincera, entusiastica alla nuova architettura viene attraversata, sin dagli anni Trenta, da una riflessione specifica nella quale il progetto scopre nel paesaggio l’elemento di sintesi tra ambiente naturale e storia. In quest’ottica i Cromatismi Architettonici mostrano con l’evidenza di un’opera manifesto un paesaggio urbano astratto e onirico che, se da un lato rappresenta una critica alla falsità della città eclettica, dall’altro apre il dibattito urbanistico funzionalista a percorsi nuovi e inesplorati. Similmente, le bellissime residenze signorili che Bottoni realizza negli anni Trenta e Quaranta evidenziano come il paesaggio divenga elemento privilegiato della composizione architettonica, capace di garantire un confronto tra il Moderno, la storia e il luogo. Un passaggio fondamentale per capire i rapporti che legano l’architettura di Piero Bottoni al paesaggio è rappresentato dalla sua partecipazione ai Ciam, con particolare riferimento alla Carta di Atene. La scala geografica del problema urbanistico sancita dalla Carta permette a Bottoni di pensare alla progettazione architettonica e del territorio in termini unitari. Esempio emblematico di questo passaggio è il Piano Regolatore della Valle d’Aosta realizzato nel 1936. Quest’episodio rappresenta un vero e proprio spartiacque per la disciplina urbanistica in Italia che per la prima volta si confronta con una scala regionale, misurandosi con la complessità territoriale e concentrandosi sull’interesse sociale collettivo. Lo studio del quartiere urbano, dei suoi rapporti con la città e con il paesaggio, raggiunge compimento con il progetto del Quartiere Sperimentale all’Ottava Triennale del 1946. Il QT8 impegna Bottoni per anni; il progetto, nato dall’idea di realizzare un quartiere sperimentale permanente, diviene per l’architetto milanese momento di riflessione sulla ricostruzione. Il drammatico problema abitativo dell’immediato dopoguerra viene affrontato su scala urbana; il quartiere, che si sviluppa all’interno di un grande parco, trova nell’elemento naturale il fattore qualificante dell’espansione della città, mentre l’invenzione del Monte Stella segna con la sua monumentalità la nuova porta Nord-Ovest di Milano. Questa collina verde, modellata da Bottoni sui cumuli delle macerie postbelliche, diviene simbolo di una ricostruzione che non risponde solo a bisogni contingenti ma che ridisegna la città attraverso una nuova geografia: un’orografia inaspettata, paradigma e ossimoro di natura e artificio. Il rapporto con il paesaggio contraddistingue in maniera evidente la produzione architettonica e urbanistica di Piero Bottoni in Toscana. Gli edifici progettatati per Livorno, Massa e Firenze sono concepiti come strumenti per abitare il paesaggio e contemporaneamente il paesaggio diviene materiale per la costruzione del manufatto architettonico. Il tema dell’abitazione proiettata nel paesaggio, inaugurato con Villa Latina del 1929, è tratto caratterizzante delle residenze che Bottoni progetta in Toscana. In questo senso, Villa dello Strologo a Livorno non è concepibile se disgiunta dal parco, così come la Casetta nella pineta ai Ronchi in assenza della pineta, o Villa Davoli in località la Ruota privata dell’ampio panorama su Firenze. I piani regolatori realizzati nel dopoguerra da Bottoni per Siena e San Gimignano consentono all’architetto milanese di confrontarsi con il tema della città d’arte. In questi piani, esempi lungimiranti di progettazione urbanistica, la riflessione sul centro storico, sui rapporti tra questo e le nuove espansioni urbane, va oltre il recupero e la conservazione dell’antico. La tutela della città d’arte viene affrontata non solo nelle emergenze monumentali, ma all’interno del proprio territorio. La struttura urbana viene per questo analizzata e progettata preservando i rapporti dialettici e morfologici che intercorrono tra masse murarie e paesaggio. In quest’ottica le espansioni vengono previste come nuclei autonomi compatti, introducendo vincoli di inedificabilità che preservino la percezione della città nei suoi legami con il paesaggio.

Abstract:
Questa ricerca si occupa dello spazio aperto della città convessa, vale a dire quella particolare condizione della modernità caratterizzata da un piano libero sul quale gli oggetti architettonici si collocano autonomamente. La domanda da cui prende le mosse è se davvero il pensiero urbano del Novecento sia l’esito di un implacabile desiderio di tabula rasa, o se piuttosto gli architetti di questa fase cerchino il proprio contesto di riferimento in un rinnovato rapporto con la natura, ricodificando i modelli insediativi fin nella loro texture costitutiva. Con un ribaltamento del punto di vista, che metta al centro dell’attenzione lo “spazio tra le cose” piuttosto che le cose stesse, si vedrà come il “progetto della natura”, lungi dall’avere funzione riempitiva di un campo isotropo e indeterminato sia, al contrario, una componente fondamentale della costruzione urbana, in grado di orientare e condizionare la forma della nuova città-territorio. Attraverso alcune realizzazioni significative – il QT8 di Piero Bottoni, Decima di Luigi Moretti, la Cité des Courtillères di Émile Aillaud e Lafayette Park, progetto americano di Mies, Hilberseimer e Caldwell – si tenterà di comprendere come la città possa essere progettata a partire da un’idea molto forte di spazio aperto, il quale già negli anni Cinquanta è informato di acquisizioni teoriche mature e strumenti operativi capaci di guidare, a monte, il progetto della città. Alcune categorie critiche sono messe a sistema per portare alla luce un’inaspettata costellazione di figure spaziali ricorrenti. L’obiettivo è tracciare delle linee di senso che, dallo spazio aperto della modernità, conducono fino alle più recenti acquisizioni sul progetto di paesaggio. In effetti, se si guarda alle posture contemporanee del “fare paesaggio”, si possono osservare non pochi punti di contatto.

Abstract:
For twenty years, the architecture of Italian rationalism through the digital modelling has been investigated. Very often, the production of a model and the consequent representation of tridimensional views, in many case studies, as outcome of the research on architecture have been considered. Actually, the digital model, intended as a critical tool, has to be conceived as a ‘starting point' for graphic analysis of architecture and not as the outcome. Indeed, it is associated to other graphics, sometimes not ‘deducted' from the model, useful for the understanding/translation of architecture. The construction of the model is not the construction of a simple image, operation, which is often carried out for the representation of the project, but it is the hermeneutic and critical result of the drawing tending to the analysis of the form, which is the true object of ‘imitation'. This study wants to contribute to the construction of a digital archive on the topic of the single-family house investigated by Piero Bottoni and Luigi Vietti.

Abstract:
The application of recycled compound concrete made of demolished concrete lumps (DCLs) and fresh normal concrete in pier foundation can effectively improve the utilization efficiency of construction waste resources. In this study, two prefabricated pier foundations based on recycled compound concrete (dimension of Ø800 × 2500 mm and Ø1000 × 2500 mm) and two cast-in-place pier foundations based on ordinary concrete (dimension of Ø800 × 2500 mm and Ø1000 × 2500 mm) were tested. Special attention was devoted to the load-settlement curve characteristics of the precast pier foundation of compound concrete, the load transfer law of the pier-soil system, the soil pressure distribution at the bottom of the pier, and the failure mode. The results showed that the Q-S curve of precast concrete pier foundation made of recycled compound concrete is slow deformation at loading, which is consistent with that of cast-in-place concrete pier foundation. The load transfer theory of pier-soil system is established, and its accuracy is verified by experimental analysis. The precast foundation of recycled compound concrete is the same as the cast-in-place foundation of ordinary concrete. The failure form of prefabricated pier foundation made of recycled compound concrete was a local shear failure, while the failure form of ordinary concrete cast-in-place pier foundation was piercing-type shear failure. The feasibility of relevant theoretical methods for calculating the vertical ultimate bearing capacity is examined.

Abstract:
Piezoceramic materials exhibit different types of nonlinearities depending upon the magnitude of the mechanical and electric field strength in the continuum. Some of the nonlinearities observed under weak electric fields are: presence of superharmonics in the response spectra and jump phenomena etc. especially if the system is excited near resonance. It has also been observed by many researchers that, at weak alternating stress fields, the relationship between the piezoelectrically induced charge and applied stress in ferroelectric ceramics, has the same form as the Rayleigh law (for magnetization versus magnetic field) in ferromagnetic materials. Applicability of the Rayleigh law to the piezoelectric effect has been demonstrated for Lead Zirconate Titanate ceramics by many researchers and their experimental results indicate that the dominant mechanism responsible for piezoelectric hysteresis and the dependence of the piezoelectric coefficient on the applied alternating stress is the pinning of non-180° domain walls. In this chapter, the Rayleigh law for ferromagnetic hysteresis has been modified and incorporated in a nonlinear electric enthalpy function and then applied in the analysis of hysteresis behavior of piezoelectric continua. Analytical solutions have been derived for a cantilever beam actuated by two piezo-patches attached to the top and bottom of the beam and excited by opposite electric fields. Analysis has been carried out at different electric field excitations of varying amplitude and frequencies and the results have been compared with the available experimental results from literature.

"at the bottom flange and six on the web. Eight gages were installed at the approximate locations of the maximum positive and maximum negative moments. At each location four gages were installed; one at the top flange, one at the bottom flange and two equally spaced on the web. Finally, four gages were installed on two cross-bracing diaphragms between girders 5 and 6 one at about mid-span and the other over the support. The gages at each cross-bracing were located one on a chord member and the other on a diagonal. The weldable strain gages used are constantan alloy gages with backing and encapsulation of polyimide film. The gages are bonded to stainless steel carriers, 0.005 in. thick, and have exposed copper coated integral solder tabs to which wire cables were soldered directly. The cables were connected to three switch and balance units (10 channels each unit) thus providing a method of sequentially reading the strain gage information on a single strain indicator. As mentioned earlier the bridge was tested during construction; hence strain measurements were taken due to the weight of the wet concrete before and after three placements. After the deck slab has reached its design strength, and before placing the bituminous wearing surface, strain measurements were taken due to truck loads positioned at sixteen different positions on the bridge deck. Eight 3-axel trucks weighting about 60 kips each were used. The overall length of each truck is 24'-8" and the overall width is 8' 6". The aforementioned sixteen positions of the trucks consist of the following, In twelve positions the trucks were forming a line about 200 ft long at mid-span A between pier 3 and pier A,."

Abstract:
In this paper the authors build upon the single degree of freedom ice-structure interaction model initially proposed by Matlock, et al. (1969, 1971). The model created by Matlock, et al. (1969, 1971), assumed that the primary response of the structure would be in its fundamental mode of vibration. Modal analysis is used in this study, in which the response of each mode is superposed to find the complete modal response of the entire length of a pier subject to incremental ice loading. In Matlock, et al., the physical system is a bottom supported pier modeled as a cantilever beam. Realistic conditions such as ice accumulation on the pier modeled as a point mass and uncertainties in the ice characteristics are introduced in order to provide a stochastic response. The impact of number of modes in modeling is studied as well as dynamics due to fluctuations of ice impact height as a result of typical tidal fluctuations. A Poincare´ based analysis following on the research of Karr, et al. (1992) is employed to identify and periodic behavior of the system response. The intention of this work is to provide a foundation for future work coupling multiple piers and connecting structure for a comprehensive ice-wind-structural dynamics model.

Abstract:
Tacoma Narrows Constructors (TNC) is building a new suspension bridge in Tacoma, close to Seattle, Washington State, USA. The new bridge will be built just south of the existing bridge mounted on two caissons, referred to as East Caisson (Tacoma side) and West Caisson (Gig Harbor side). Each pier is about 80’ wide and 130’ long in plan. The mooring system for each caisson consists of two sets of mooring lines: lower and upper. Each set consists of 16 mooring lines. The lower 16 lines consist of anchors that form a radius of about 300 feet. The fairlead locations for these lower 16 lines are kept constant throughout the construction process. These 16 lines are hooked-up after the caisson is towed from the harbor and positioned at the site. For the upper 16 lines (except three lines on East Pier), the anchor locations form a radius of 600’. The fairlead locations for these upper 16 lines vary based on the draft. Due to the proximity of the proposed caissons to the existing piers and the varying bottom topography, considerable turbulence and vortex shedding is expected which will cause current induced dynamic forces on the caissons. This paper describes the design and analysis of this multi-line mooring system for Tacoma Narrows Bridge caissons, based on the construction sequence in the floating condition. The analysis involved optimizing the anchor locations and the line pretensions, determining the dynamic motions of the caissons, maximum line loads, and corresponding safety factors. The paper includes the hydrodynamic analysis for added mass, and damping, the methodology used for the nonlinear moored caisson analysis (MOTSIM), and the validation of the design tool with other similar models (e.g., StruCAD*3D). The results of the analysis and design are discussed.

Abstract:
A new suspension bridge is being built over the Tacoma Narrows, Washington. The bridge will be placed on a structure mounted on two large concrete caissons. The caissons are being constructed in a floating position by pouring concrete at site. During this construction period, the floating caissons are moored in place and will be subject to high currents in the Narrows at a range of drafts. In order to investigate the motions of the caisson and the mooring line loads, physical model tests were performed at a scale of 1:100 at HR Wallingford (HRW). The actual bottom contours of the Narrows near the construction site was duplicated in the model. The catenary mooring lines were highly nonlinear. The current forces and moments on the floating caisson included steady and oscillating components due to flow separation and vortex shedding. There is an existing bridge mounted on two piers in the vicinity of the new caissons, which introduced an appreciable flow interference effect. The tests were conducted in both the ebb and flood flow directions so that the effect of the shadowing of the caisson-pier pair could be studied in the tests. The recorded results of the elastic mooring tests were compared in terms of the maximum measured tensions with a time-domain dynamic motion simulation program, MOTSIM. The results of this comparison are presented in this paper.

Abstract:
A new suspension bridge is being built over the Tacoma Narrows, Washington. The bridge will be placed on a structure mounted on 2 large concrete caissons, which will be exposed to strong currents. The piers are of rectangular section with chamfered edges in the upper portion. The caissons are being built at site while floating and moored in high currents. There are no known analytical methods or experimental data available on such structures at high Reynolds number. In order to determine the forces on the caisson due to current, a series of scaled physical model tests of one of the caissons was carried out. The forces on the new caisson were measured in the presence of the existing bridge pier and the bottom contours of the Narrows were accurately modeled. The model scale was chosen as 1:100 and the tests were performed for the caisson at different drafts. This paper describes the test setup, and measurement system for a series of fixed caisson tests and demonstrates the consistency of the test data. The measured inline drag and transverse lift forces on the fixed caisson at different drafts are presented and the effect of the fluid velocity and flow vorticity on the frequency contents in the forces is discussed. The interaction effect of the neighboring existing pier on the current forces of the new caisson is investigated. Since the measured forces were applied in the design analysis of the caissons, the scaling effect of the model test is also discussed. This paper is accompanied by two other papers, which form a group of three papers related to the project describing the current excitation on the caisson and the associated caisson responses. The other two papers in succession are ref. [1] and ref. [2]. The paper in ref. [1] describes the numerical computation of the current forces on the caisson by a 3-D CFD analysis, while the ref. [2] uses the information from these two papers to determine the motion response of the caissons and the mooring line tensions.

Full text
Abstract:
Longitudinally Coupled Prefabricated Ballastless Track (LCPBT) system was firstly applied on Suining-Chongqing experimental railway line and Beijing-Tianjin intercity railway line. LCPBT track structure is longitudinally continuous, with fixing a 5-cm-thick hard foam board above every bridge structure joints, between bridge protection layer and the continuous concrete base to reduce detrimental fastening pulling force in case of great rotation angle or displacement. Hard foam board ensures a steady deformation transition, and we calculate its compressive stress, compression and cubical elasticity coefficient Q, for fulfilling force-bearing and deformation requirements. Taking a two-span, simple supported beam, each with 32-m-long bridge for instance, an integral finite element model of continuous welded rail -coupled track slab -coupled concrete base –bridge beam was established, in which a vertical compression amount under 9 different load cases. The maximum bottom tensile stress of concrete base, maximum compressive stress and compression amount of hard foam board are gained from computation results. Besides, Q-value and the control value of rotation angle at bridge structure joints are suggested in this paper. The key findings are: a) under simultaneous actions of train load and beam rotation angle, the maximum bottom tensile stress of concrete base does not exceed its threshold as 250 kPa, given a Q-value of 0.5 N/mm3; b) considering the uniformity of track stiffness and track regularity, a greater Q-value is preferable and we recommend the Q-value as 0.5 N/mm3; c) the beam rotation angle at bridge structure joints should be less than 1.4, including the load cause of uneven settlement of adjacent bridge piers, uneven settlement of adjacent bridge foundation; d) uneven settlement of adjacent bridge foundation on the same bridge pier must be strictly controlled to avoid affecting the service life of hard foam board.

Abstract The converse piezo effect is used to minimize the deflection of a given point for antisymmetrically laminated rectangular plates. The piezoelectric layers are bonded to the top and bottom surfaces of the laminate and are subjected to an electrical field. The deformation generated by the piezo effect counteracts the deflections induced by mechanical and/or thermal loads. Moreover, the ply angles can be used as additional design variables to minimize the deflection. In the numerical examples, the mid-point of the plate is specified as the point deflection of which is to be minimized. It is shown that, depending on the magnitudes of the mechanical and thermal loads, the deflection of this point can be reduced to zero by applying a certain voltage to piezoelectric layers.

Abstract:
One of the major concerns affecting the safety of bridges with foundation supports in river-beds is the scouring of river-bed material from bridge supports during floods. Scour is the engineering term for the erosion caused by water around bridge elements such as piers, monopiles, or abutments. Scour holes around a monopile can jeopardize the stability of the whole structure and will require deeper piling or local armoring of the river-bed. About 500,000 bridges in the National Bridge Registry are over waterways. Many of these are considered as vulnerable to scour, about five percent are classified as scour critical, and over the last 30 years bridge failures caused by foundation scour have averaged about one every two weeks. Therefore it is of great importance to predict the correct scour development for a given bridge and flood conditions. Apart from saving time and money, integrity of bridges are important in ensuring public safety. Recent advances in computing boundary motion in combination with mesh morphing to maintain mesh quality in computational fluid dynamic analysis can be applied to predict the scour hole development, analyze the local scour phenomenon, and predict the scour hole shape and size around a pier. The main objective of the present study was to develop and implement a three dimensional iterative procedure to predict the scour hole formation around a cylindrical pier using the mesh morphing capabilities in the STARCCM+ commercial CFD code. A computational methodology has been developed using Python and Java Macros and implemented using a Bash script on a LINUX high performance computer cluster. An implicit unsteady approach was used to obtain the bed shear stresses. The mesh was iteratively deformed towards the equilibrium scour position based on the excess shear stress above the critical shear stress (supercritical shear stress). The model solves the flow field using Reynolds Averaged Navier-Stokes (RANS) equations, and the standard k–ε turbulence model. The iterative process involves stretching (morphing) a meshed domain after every time step, away from the bottom where scouring flow parameters are supercritical, and remeshing the relevant computational domain after a certain number of time steps when the morphed mesh compromises the stability of further simulation. The simulation model was validated by comparing results with limited experimental data available in the literature.

LOAD TRANSFER MECHANISM OF STEEL GIRDER-RC PIER CONNECTION IN COMPOSITE RIGID-FRAME BRIDGE. The Hong Kong Institute of Steel Construction, August 2022. http://dx.doi.org/10.18057/icass2020.p.286.

Full text
Abstract:
The composite rigid-frame bridge, where the steel girder and the reinforced concrete (RC) pier are rigidly connected, has a high bearing capacity and superior long-term performance. The steel girder-RC pier connection is the critical detail for the design of such a structural form. To this end, a detailed review of composite rigid-frame bridges in China and abroad was carried out to summarize various forms of connections and evaluate their applicability. A novel connection type was then proposed to improve the connective performance between steel plate girders and RC piers. Threedimensional finite element models were further developed to investigate the force transfer mechanism, accounting for the impact of concrete stress, shear force in the connectors, and stress of steel plates. The results indicated that the proposed connection was capable of transmitting external loads reliably, and its ultimate bearing capacity exceeded design loads. The shear force of perfobond connectors, the tension of reinforcement, and the bearing effect of the bottom flange provided the major force transmission path to resist the external load.
