Abstract:
In the process of structural engineering of buildings and structures with the use of direct dynamic methods the accelerogramms of earthquakes with the parameters corresponding to a specific construction site are required. Such accelerogramms could be obtained by various methods. For example, they could be produced by seismologists. However, for a structural engineer it could be required to get them processed (balancing, segregation of separate phase of impact, etc.), that is not always convenient to do. Moreover, an accelerogramm with slightly different spectral composition and lifespan, nevertheless applicable to a given construction site, could be required. Also an accelerogramm could be generated with the use of specially designed software. Although it’s not always convenient as it requires certain amount of time and could cause some difficulties during formation of original data for generation and also for obtaining correct results. In order to overcome the above-mentioned difficulties the authors proposed the representative set of synthesized earthquake accelerogramms which could be applied for various combinations of seismic properties of construction sites. The present article sets outs the principal approaches to formation of the set of earthquake accelerogramms, designated for design of buildings and structures in terms of earthquake effects. Purpose requirements to discrete accelerogramms and to the set as a whole have been disclosed, purpose characteristics of accelerogramms have been set out, clarifications and recommendations for application of the representative set of accelerogramms in practical calculations have been enclosed.

Abstract:
Spectrum-compatible seismic excitations are required when dynamic time-history analysis is used for determining the response of a structure. This paper presents results from a study on the effects of different types of spectrum-compatible excitations on the response of medium-height reinforced concrete frame buildings. Two six-storey buildings designed for Vancouver and a five-storey building designed for Montréal were used in the study. Nonlinear time-history analyses were conducted by subjecting the buildings to selected ensembles of spectrum-compatible excitations (i.e., accelerograms). The ensembles used in the study included spectrum-compatible artificial accelerograms, simulated stochastic accelerograms, and recorded earthquake accelerograms (i.e., real accelerograms) scaled to the design spectrum ordinate at the fundamental building period and to the area under the design spectrum within the predominant period range of the building. The responses of the buildings resulting from spectrum-compatible artificial accelerograms and those from scaled real accelerograms were found to be quite similar. Based on the results of this study, the scaling of real accelerograms to spectral area is preferred for obtaining spectrum-compatible accelerograms.Key words: seismic, excitation, response, spectrum, accelerogram, building, drift, curvature, ductility.

Abstract:
In earthquake-resistant design of structures, for certain structural configurations and conditions, it is necessary to use accelerograms for dynamic analysis. Accelerograms are also needed to simulate the effects of earthquakes on a building structure in the laboratory. A new method of generating artificial earthquake accelerograms is presented through adroit integration of neural networks and wavelets. A counterpropagation (CPN) neural network model is developed for generating artificial accelerograms from any given design spectrum such as the International Building Code (IBC) design spectrum. Using the IBC design spectrum as network input means an accelerogram may be generated for any geographic location regardless of whether earthquake records exist for that particular location or not. In order to improve the efficiency of the model, the CPN network is modified with the addition of the wavelet transform as a data compression tool to create a new CPN-wavelet network. The proposed CPN-wavelet model is trained using 20 sets of accelerograms and tested with additional five sets of accelerograms available from the U.S. Geological Survey. Given the limited set of training data, the result is quite remarkable.

Abstract:
Characteristics of a nonstationary process obtained by modulating the amplitude and frequency of a stationary process differ from those of an oscillatory process. An accelerogram recorded in the soft soil of Mexico City during the 1985 earthquake serves to calibrate both nonstationary models. Responses of linear and nonlinear single-degree-of-freedom systems indicate that the process with modulated amplitude and frequency is preferable for reliability studies. Coefficients of variation of ductility demands of systems excited with accelerograms generated by the model with modulated amplitude and frequency are close to those corresponding to actual accelerograms.

Abstract:
ABSTRACT Permanent ground offsets, constituting a prime dataset for constraining final fault-slip distributions, may not be recovered straightforwardly by double integration of near-field accelerograms due to tilt and other distorting effects. Clearly, if a way could be found to recover permanent ground offsets from acceleration records, then static datasets would be enlarged, and thus the resolution of fault-slip inversions would be enhanced. Here, we introduce a new approach for extracting permanent offsets from near-field strong-motion accelerograms. The main advantage of the new approach with respect to previous ones is that it corrects for source time functions of any level of complexity. Its main novelty is the addition of a constraint on the slope of the ground velocity spectra at long periods. We validated the new scheme using collocated accelerograms and Global Navigation Satellite Systems (GNSS) records of the 2011 Mw 9 Tohoku-Oki earthquake. We find a good agreement between accelerogram-based and GNSS-based ground offsets over a range of 0.1–5 m. To improve the spatial coverage of permanent ground offsets associated with the 2004 Parkfield earthquake, near-field accelerograms were baseline corrected using the new scheme. Static slip inversion of the combined GNSS-based and accelerogram-based ground displacements indicates appreciable seismic moment release south of the epicenter, about 5 km into the Cholame section of the San Andreas fault. We conclude that the strong shaking observed to the south of the epicenter is directly related to the slip in that area and is not the result of local amplification.

This paper presents the method of establishing artificial accelerogram for analysis and calculation of structures in accordance with seismic characteristics and earthquake risk in one specific construction areas in Vietnam. The artificial accelerogram allow to analyze nonlinear or linear dynamic behavior of the structures in time series in accordance with Vietnam National Standards for Design of structures for earthquake resistances (TCVN 9386: 2012) and seismic parameters specified in Vietnam Building Code on Natural Physical and Climatic Data for Construction (QCVN 02:2009-BXD). The accelerograms are also used as input parameters for shaking table tests by Vietnam's most modern sharking table at the Vietnam Institute for Building Science and Technology.

Abstract:
Most of the remarkable digital strong motion accelerogram from the June 9, 1980 Mexicali Valley earthquake (Mw = 6.4) has been recovered by careful analysis. Peak horizontal accelerations (.98g, .87g) and duration were similar to the values for the recent Superstition Hills earthquake. The vertical accelerogram clipped the 1g instrument several times. The records provide an important example of near fault accelerations from a second earthquake in the deep sediments of the Imperial Mexicali Valley (the other being the records from the 1979 Imperial Valley earthquake). The 1980 accelerograms are important because they were not affected by foundation filtering, as were the records for the Imperial Valley 1940 earthquake, and because they illustrate the damaging near-source, intermediate frequency velocity pulse associated with passage of the rupture front.

Abstract:
The aim of this paper is to analyse the damage on gravity dams through artificial earthquakes from two methods. The first procedure defines the performance and the response curve of concrete gravity dams using a harmonic function which establishes linear displacements. The other procedure to obtain the artificial earthquake defines the power spectral density function consistent with the response spectrum. This artificial accelerogram is necessary to quantify the response curve of concrete gravity dams in the time domain. The seismic activity in Spain is not frequent, therefore it is often difficult to select real accelerograms to perform a complete seismic analysis, which makes artificial accelerograms extremely useful. Finally, combining these two procedures, a damage index is determined for assessing the crack’s magnitude. These both efficient and practical procedures are useful to develop further complicated analysis.

Abstract:
Estimating the reduction factor for calculating massive reinforced concrete bridge piers was made. For this purpose a quasi-static “force-displacement” diagram was built up using the ANSYS software. This diagram has the form of a bilinear one, and the character of the bilinearity depends on the diameter of the reinforcing bars insignificantly. The percentage of reinforcement affects only the moment when all reinforcement bars begin to flow. The reinforcement flow takes place in the displacement interval from 3 to 5 cm. The collapse will occur when the reaction of the bearing part goes beyond the pier cross-section at pier displacements from 5 to 20 cm. Using “force-displacement” diagram, the behavior of the single-mass model with a bilinear deformation diagram and the limit displacement of 20 cm was analyzed. Then, it became possible to obtain for each accelerogram the limit elastic displacement and the limit position of the point corresponding to the maximum structure displacement during structure oscillations. It was done using real accelerograms of earthquakes with intensity 9 on the MSK scale without normalizing their amplitudes. In this case, long-period accelerograms had smaller peak accelerations, but resulted in greater plastic deformations. As a result, no evident dependence of plastic deformation on the input spectral composition was found and the value of reduction factor K1 turned out to be 0.25-0.27. However, it is shown that this reduction factor cannot be used to make transition from seismic loads obtained on the basis of time-history analysis by accelerograms to design loads.

Abstract:
Flat ceramic tiles are widely used as protective and aesthetic construction elements in urban building facades. Under the effect of extreme temperatures from the weather seasonality, bonded joints of these tiles undergo thermal cycle’s loads. In this work, a dynamic technique based on vibration metrology is implemented. This procedure consists in the analysis of accelerograms obtained in bonded ceramic tiles from low-intensity impact loads. A corresponding study carried out with finite element modelling allowed an accurate calibration of mechanical parameters of the tile/adhesive pair as well as the estimation of a vibration dissipation factor. Several test specimens subjected to a defined period of thermal cycles stressing were also analysed for the mentioned accelerogram and an expression for the ageing estimation of the mechanical properties of the bonded joints in the tiles was obtained.

Abstract:
La città di Bologna, così come tutta la penisola italiana, fa parte di un territorio in cui il rischio sismico è elevato. In questo lavoro di tesi viene proposto un modello numerico del terreno di fondazione delle Due Torri di Bologna sviluppato al fine di analizzarne la risposta sismica locale. Con lo scopo di ottenere un modello rappresentativo più possibile delle condizioni reali è stato eseguito un accurato studio geologico, geotecnico e sismico del substrato in esame. La selezione degli input sismici da utilizzare durante le analisi è avvenuta mediante l’uso del software REXEL e, in particolare, si è fatto riferimento all’European Strong Motion Database (ESD). La validazione del modello sviluppato è avvenuta attraverso il confronto dei risultati tra il codice di calcolo PLAXIS e un codice di calcolo che svolge analisi visco-elastiche lineari nel dominio delle frequenze, MARTA. È stata, quindi, analizzata l’influenza che possono avere l’estensione del modello e le condizioni al contorno di base (linear elastic o compliant base) ai fini della valutazione della risposta sismica locale, insieme con la variazione delle condizioni al contorno laterali, viscous o tied degrees of freedom. Inoltre, si sono valutati gli effetti di input sismici di diversa entità. Nel caso specifico, si è visto che impiegare un contorno laterale del tipo tied degrees of freedom ha apportato dei vantaggi, sia per l’affidabilità dei risultati che sono gli stessi ricavati mediante MARTA, sia per il fattore tempo. Di contro, si è visto che per bassi livelli tensionali, PLAXIS potrebbe sottostimare la rigidezza. I risultati ottenuti nell’ambito di questo progetto di tesi costituiscono un punto di partenza per eventuali studi futuri, che prevedono la realizzazione di strutture tali da simulare le Due Torri, per analizzare l’interazione dinamica terreno/struttura.

Abstract:
Con questa tesi è stata studiata una metodologia per la previsione di scenari di danno post terremoto. La procedura, basata su un approccio empirico, è stata sviluppata per categorie di costruzioni con caratteristiche strutturali e dinamiche omogenee, e si applica a scala territoriale. Il procedimento consiste nell’associare al danno procurato da uno o più eventi i corrispondenti parametri di intensità sismica e conservare l’informazione in schede di correlazione, in modo da farne uso, come riferimento, in caso di nuovo evento sismico. La consultazione di tali schede, che costituiscono un archivio degli effetti causati da una serie di eventi per la categoria di costruzioni in esame, permette di formulare una previsione di danno non appena si dispone dei parametri di intensità del nuovo evento. La procedura è stata applicata nel caso degli edifici produttivi emiliani costruiti in assenza di criteri antisismici. Sono state analizzate le scosse, di magnitudo maggiore di 5, avvertite in Emilia a partire dal 1996 (crisi sismica EMILIA 2012, terremoto di Poviglio (PR) del 2012, terremoto di Bagnolo in Piano (RE) del 1996), aventi l’epicentro in zone con un’alta densità di edifici appartenenti alla categoria in esame. L’indagine ha permesso di individuare una prima ipotesi di soglie di danno, riferite principalmente, nel caso degli edifici produttivi, a parametri di intensità sismica dipendenti dalla velocità e dallo spostamento. La procedura è stata applicata inoltre nel caso della sequenza sismica del Centro Italia (2016-2017) per gli edifici in muratura di Norcia (PG) e per gli edifici produttivi di Arquata del Tronto (AP) e Muccia (MC).

L’obbiettivo della tesi è quello di andare a contestualizzare il metodo "Direct Five Step Procedure" (DFSP) per la progettazione di un sistema di dissipatori fluido-viscosi in un adeguamento/miglioramento sismico di un edificio esistente ed integrando la procedura tenendo conto della capacità duttile della struttura. Per fare ciò si è preso in esame un edificio esistente situato a L’Aquila caratterizzato da un rapporto C/D (capacità/domanda) intorno a 0.2-0.3 così da rendere necessario l’accoppiamento di dissipazione viscosa tramite smorzatori e di dissipazione isteretica attraverso il danneggiamento negli elementi strutturali (travi e pilastri). Imponendo come condizione η = ηξ * ηq (fattore di riduzione della risposta sismica costituito da due contributi: uno viscoso ed uno isteretico) ed utilizzando la DFSP per la progettazione degli smorzatori viscosi si è andato a studiare il comportamento della struttura tramite analisi dinamiche non lineari (come imposto da normativa), utilizzando diverse taglie di smorzatori e confrontando i fattori di riduzione di target e quelli ottenuti a valle delle analisi.

Abstract:
Smooth design spectra are generally used to describe the seismic excitation provided by the maximum design earthquake for safety evaluation of critical facilities located in Eastern Canada. However, a comprehensive study of the inelastic behaviour of critical structural systems requires step-by-step inelastic analysis in the time domain.
This thesis presents a study of inelastic seismic analysis of short-period structures subjected to ground motion acceleration time histories compatible with Eastern Canadian conditions and defined (i) from historical records scaled to the smooth design spectrum intensity, (ii) from spectrum-compatible accelerograms generated by random vibration theory, and (iii) from the modification of the Fourier Spectrum coefficients of historical records while preserving the original phase angles. The ductility demand, the input energy, the hysteretic energy, the number of yield events, and other performance indices, are examined in parametric analyses to identify the type of earthquake motions that is critical for earthquake resistant design of ductile short-period structures. The linear and cracking responses of concrete gravity dams of three different heights (90m, 45m, and 22.5m), that exhibit a brittle response to strong ground shaking, are also examined for the different types of spectrum-compatible accelerograms. It is generally concluded that in the absence of suitable spectrum-compatible historical accelerograms, either historical records with modified Fourier spectra or synthetic records can be used to evaluate the linear structural response. For nonlinear analysis, historical records with modified Fourier amplitude spectra tend to produce closer results to those obtained from real earthquakes for cumulative damage indices, as compared to the results computed from synthetic accelerograms.

Abstract:
Este trabalho apresenta um estudo comparativo entre análises no domínio do tempo e análises espectrais, como forma de sugerir uma abordagem alternativa para o projeto de pontes de seção celular submetidas à ação de terremotos. Com esse propósito, desenvolveu-se um programa em linguagem JAVA para a geração de sismos artificiais, usando como base o Eurocode 8. A saída do programa foi utilizada para o desenvolvimento de um estudo de caso, que consiste em uma modelagem simplificada no software ADINA, de um vão de 21 m da Ponte Alverca, em Portugal. Após a extração e comparação de resultados dos dois métodos, é possível perceber que o método alternativo proposto - no domínio do tempo, que consiste na aplicação de acelerogramas artificiais ao modelo - possui resultados bastante coerentes com a análise espectral, além de ser mais recomendado se efeitos geométricos ou fisicamente não lineares forem considerados na modelagem.
This work presents a comparative study between time-domain analysis and spectral analysis, as a way of suggesting an alternative approach for treating cell section bridges subjected to earthquakes. To reach this goal, it was developed a program in JAVA language for the artificial earthquakes generation, using the Eurocode 8 as a basis. The program output was used for a case study that consists in a simplified modeling using ADINA software, of a twenty-one-meter-long span of Alverca Bridge, in Portugal. After the results extraction of both methods, it is possible to notice that the alternative method - in the time-domain, which consists of the application of artificial accelerograms to the model - has fairly consistent results with spectral analysis, not to mention that it is the most suitable one, in case geometrical or physical non-linearities are considered in the modelling.

Abstract:
Abstract Relationships between seismic action, system response and relevant damage levels in industrial plants require a solid background both in experimental data, due to the high level of non-linearity and seismic input. Besides, risk and fragility analyses depend on the adoption of a huge number of seismic records usually not available in a site-specific analysis. In order to manage these issues and to gain knowledge on the definition of damage levels, limit states and performance for major-hazard industrial plant components, we present a possible approach for an experimental campaign based on a real prototype industrial steel structure. The investigation of the seismic behaviour of the reference structure will be carried out through shaking table tests. In particular, tests are focused on structural or process-related interactions that can lead to serious secondary damages as leakage in piping systems or connections with tanks and cabinets. The aforementioned test program has been possible thanks to the adoption of: i) a number of artificial spectrum-compatible accelerograms; ii) a ground motion model (GMM) able to generate a suite of synthetic time-histories records for specified site characteristic and earthquake scenarios. More precisely, GMM model parameters can be identified by matching the statistics of a target-recorded accelerogram to the ones of the model in terms of faulting mechanism, earthquake magnitude, source-to-site distance and site shear-wave velocity. As a result, the stochastic model, based both on these matched parameters and on filtered white-noise process, can generate the ensemble of synthetic ground motions capable of capturing the main features of real earthquake ground motions, including intensity, duration, spectral content and peak values. Moreover, the synthetic records are selected to target specific damages and limit states in industrial components. Finally, by means of the combination of artificial and synthetic accelerograms, a seismic vulnerability assessment of both the whole structure and relevant industrial components can be carried out.
