Abstract:
Movement of bridge abutment is a significant issue affecting the overall reliability and safety of the structure. However, despite considerable consequences, potential movement of abutment is usually not considered in design of bridges for serviceability and abutments are generally designed as fixed elements. Theoretical analysis of bridge abutment and deck design provides background knowledge of reactions that should be anticipated and accounted for. Case studies of bridges experiencing movements and rotations show that practical outcomes often deviate from theoretical expectations. The research presented in this paper, aims to develop a better understanding of abutment stability from both a design and maintenance point of view. This paper includes an in-depth case study of the Kanahooka Road Overbridge in New South Wales, Australia. The results of a full bridge inspection leading to identification of multiple serviceability issues caused by movement of abutments are presented. Moreover, a systematic methodology is implemented, to identify potential remedial options for treatment of abutment movement. The knowledge gained through this case study has led to the development of a model for the management of abutment movement.

Abstract:
It is well recognized that leaking expansion joints at the ends of bridge decks have led to the premature deterioration of bridge components. The elimination of these maintenance-prone joints not only yields immediate economic benefits but also improves the long-term durability of bridges. In Ontario, Canada, “jointless” bridges have been used for many years. Recently, the use of two main types of these bridges has increased dramatically. The first type is an “integral abutment” bridge that comprises an integral deck and abutment system supported on flexible piles. The approach slabs are also continuous with the deck slab. The flexible foundation allows the anticipated deck movements to take place at the end of the approach slab. Control joint details have been developed to allow movements at this location. The second type is a “semi-integral abutment” bridge that also allows expansion joints to be eliminated from the end of the bridge deck. The approach slabs are continuous with the deck slab, and the abutments are supported on rigid foundations (spread footings). The superstructure is not continuous with the abutments, and conventional bearings are used to allow horizontal movements between the deck and the abutments. A control joint is provided at the end of the approach slab that is detailed to slide in between the wing walls. Some of the design methods and construction details that are used in Ontario for integral and semi-integral abutment bridges are summarized. A review of the actual performance of existing bridges is also presented.

Abstract:
Integral Abutment Bridges are widely utilized around the world because they offer a design alternative minimizing the potential construction and maintenance difficulties associated with expansion joints in other types of bridges. However, integral bridge systems also have certain issues that result from the absence of expansion joints. This is because temperature changes induce cycles of elongations and shortenings in the bridge deck which lead to rotational movements in bridge abutments against and away from the retained soil. This phenomenon may develop long term problems in terms of settlement of the backfill at the bridge approach and escalation in the lateral earth pressure acting on the bridge abutments. This paper aims to investigate the approach settlement and lateral earth pressure development in integral bridges abutments using finite element modelling of a concrete bridge abutment and the adjoining soil using the ABAQUS software. The paper presents a parametric study of the effects imposed by abutment movements on the retained soil. This study also investigates the effectiveness of using expanded polystyrene (EPS) geofoam inclusions as a remedial measure to minimize the approach settlement and lateral stress ratcheting effects in Integral Abutment Bridges.

Abstract:
Geosynthetic-reinforced soil (GRS) bridge abutments have been used on a number of bridge projects over the past decade. This adaptation of reinforced soil technology to bridge structures and their approach fills offers an excellent opportunity to simplify construction, reduce construction time, and reduce cost on structures for which this technology is appropriate. This design concept, in which the actual bridge superstructure rests upon the GRS abutment wall, minimizes differential settlement and eliminates the problematic “bridge bump” found on many structures. The technology has been adapted to both road and trail bridges. The basic design concept of GRS used in bridge abutment applications was evaluated, along with its advantages and disadvantages. Some selected case histories of GRS bridge abutments on low-volume roads and trails in Alaska and California were considered. In addition, the Mammoth bridges, in the mountains of northern California, with high design snow loads and high horizontal peak ground accelerations, afforded an opportunity to design, construct, and monitor GRS-supported spread-footing abutments under difficult service conditions.

Abstract:
The response modification factor (R factor) is a crucial parameter for calculating the design seismic forces applied to a bridge structure. This factor considers the nonlinear performance of bridges during strong ground motions. Conventional bridge structures rely on the substructure components to resist earthquake forces. Accordingly, there are R factors available in the design codes based on the type of bridge substructure system. Lateral load resisting system of Integral Abutment Bridges (IABs) in the longitudinal direction is more complex than ordinary bridges. It involves the contributions from soils behind the abutments and soil/structure interaction (SSI) in addition to existing rigid connection between the superstructure and abutments. There is no R factor available in any design code throughout the world for IABs in the longitudinal direction that considers all these parameters. In this research, the Federal Emergency Management Agency publication FEMA P695 methodology has been applied to estimate the R factor for IABs. It is found that 3.5 could be a safe and valid R factor in the longitudinal direction for seismic design of such bridges.

Abstract:
Integral abutment bridges have become a successful alternative to the traditional design procedure of using expansion joints to balance the thermal movements of bridge structures. However, there are many design and detailing variations, and uncertainties exist about the soil–structure interaction of the integral abutments. Therefore, field data from pressure cells installed behind the abutments of a 76 m long, two-span, pile-supported integral abutment bridge are the focus of this paper. The data on external displacements of the abutments are also reported. The applicability of using common theoretical passive earth pressure coefficients is assessed and it appears that the traditional methods of Coulomb and Rankine are not the best approach for predicting the earth pressure envelope. Additionally, over the monitoring period of three years, it was found that a definite conclusion regarding the ratcheting of lateral earth pressure could not be established for this bridge site. Finally, comparisons to earth pressures measured at other field studies indicate variability in the earth pressure distribution, magnitude, and behaviour over time, as these are dependent on several factors distinctive to each bridge site.

Abstract:
Integral Abutment Bridges (IABs) are joint-less bridges whereby the deck is monolithic with the abutment walls. IABs are outperforming their non-integral counterparts in economy and safety. Thermal effects introduce significantly complex and nonlinear soil-structure interaction into the response of abutment walls and piles of the IB. This paper carried out comprehensive study on voided slab system with five spans bridge each span is 17m long. The bridge has been modelled using SAP software. The abutments and pile foundations are modeled taking into consideration the soil-structure interaction. The study covered a design uniform temperature change of (10, 20, 30, 40 and 50) °C. To gain a better understanding of the mechanism of load transfer due to thermal actions, a 3D frame anal¬ysis is carried out on the above mentioned IABs. The results showed wide range of different linear and lightly non-linear relationships between temperature range, deformations and moments. The paper highlighted the serious effect of the deformations resulting from the repeated temperature change which causes drop in soil or bombing at the abutments ~ embankment contact zone.

Abstract:
Integral abutment bridges accommodate thermal superstructure movements through flexible foundations rather than expansion joints. While these structures are a common alternative to conventional design, the literature on measured field stresses in piles supporting integral abutments appears to be quite limited. Therefore, field data from strain gauges installed on the abutment foundation piles of a 76 m long; two-span integral abutment bridge are the focus of this paper. Axial load, weak- and strong-axis bending moments of the foundation piles, as well as abutment movement and backfill response, are presented and discussed. Results indicate that the abutment foundation piles are bending in double curvature about the weak axis, as a result of thermal bridge movements, and bending also about the strong axis due to tilting of the abutments. A simple subgrade modulus approach is used to show its applicability in predicting behaviour under lateral loading. In the past, much emphasis has been placed on the lateral displacements of piles and less on variations of axial load. In this paper, a new hypothesis, which offers insight into the mechanisms behind the observed thermal variations in axial load, is proposed and assessed. The data from the field monitoring are also compared with the limited data reported in the literature.

Abstract:
The behavior of an integral abutment bridge near Rochester, Minnesota, was investigated from the beginning of construction through several years of service by monitoring more than 180 instruments that were installed in the bridge during construction. The instrumentation was used to measure abutment horizontal movement, abutment rotation, abutment pile strains, earth pressure behind abutments, pier pile strains, prestressed girder strains, concrete deck strains, thermal gradients, steel reinforcement strains, girder displacements, approach panel settlement, frost depth, and weather. In addition to determining the seasonal and daily trends of bridge behavior, live-load tests were conducted. All of the bridge components performed within the design parameters. The effects from the environmental loading of solar radiation and changing ambient temperature were found to be as large as or larger than live-load effects. The abutment was found to accommodate superstructure expansion and contraction through horizontal translation instead of rotation. The abutment piles appeared to be deforming in double curvature, with measured pile strains on the approach panel side of the piles indicating the onset of yielding.

Abstract:
A study is made on the seismic behaviour of highway bridges with lead–rubber base isolation. The system of base isolation is considered as a bilinear spring. Single- and two-span highway bridges subjected to representative strong earthquake ground motion records were analyzed. The effect of various parameters such as the isolator's stiffness, pier stiffness, and pier eccentricity on the system response was evaluated.It was found that the use of base isolation shifts the fundamental frequency of the bridge system towards the longer period. Proper design of the base isolation tends to reduce the design forces on the bridge piers and is accompanied by larger displacements. Simplified design guidelines are adequate as long as the bridge system can be represented by a single degree of freedom model. The reduction in pier stiffness of a two-span bridge may increase the displacement and the force transmitted to the abutment. The increased forces at the abutments are accompanied by reduction in the shear force transmitted to the pier. Increased displacements and forces may also result when the location of the pier departs from the centre and unequal spans are created. In this case, the maximum displacements and forces occur at the abutment adjacent to the long span. Key words: dynamic, seismic, response, highway, bridges, earthquake, base isolation, design.

Abstract:
Life Cycle Assessment (LCA) is the globally the most recognised method for quantifying theimpact the a product or service has on the environment through its whole life-span. Theconstruction sector plays a key role in the depletion of the natural resources and the energyconsumption on the planet. Thus it is fundamental that an environmental assessment tool likeLCA should be in close cooperation with the construction process.This thesis focuses on the environmental impact of bridge abutments, and can be divided in twoparts.The rst one focuses on enhancing the automated design in the construction eld. A Python codeis created that focuses on creating the geometry of any type of bridge abutment and conductingthe calculations for the required concrete and reinforcement. The process is attempted to becomecompletely automated.The second part introduces three alternative designs for a bridge abutment that attempt to havethe same structural properties and cooperate successfully with the superstructure, while at thesame time utilize as little material as possible. The possible reduction in material is quantiedin environmental terms after an environmental impact assessment is performed.The results show that dierent designs can have a great impact on the reduction on the materialconsumption and on the impact that the whole structure has on the environment. The resultsin this study might provide the designers with valuable motivation and guidelines to achievehigher sustainability standards in the future.

Abstract:
Foundations of river bridges need to be protected with respect to excessive scouring. Degree of protection depends on the severity of scouring action around bridge piers and abutments. A case study is carried out to design appropriate protective measures for sequential viaducts located on Ankara-Pozant highway in Turkey. A number of analyses are conducted to obtain water surface profiles throughout the study reach. Local scour depths at piers and abutments of the viaducts are then obtained. The design process for countermeasures is performed concerning hydraulic, hydrologic, constructional, and economical requirements. To this end, riprap, partially grouted riprap, and articulated concrete blocks are studied in these view points. A criterion based on a selection index, which is defined by the National Cooperative Highway Research Program in the USA, is applied in this study. Implementation of partially grouted ripraps at infrastructural elements is found to be an appropriate solution.

Abstract:
Skewed bridges have exhibited poorer performance during lateral earthquake loading in comparison to non-skewed bridges (Apirakvorapinit et al. 2012; Elnashai et al. 2010). Results from numerical modeling by Shamsabadi et al. (2006), small-scale laboratory tests by Rollins and Jessee (2012), and several large-scale tests performed by Rollins et al. at Brigham Young University (Franke 2013; Marsh 2013; Palmer 2013; Smith 2014; Frederickson 2015) led to the proposal of a reduction curve used to determine a passive force skew reduction factor depending on abutment skew angle (Shamsabadi and Rollins 2014). In all previous tests, a uniform longitudinal load has been applied to the simulated bridge abutment. During seismic events, however, it is unlikely that bridge abutments would experience pure longitudinal loading. Rather, an inclined loading situation would be expected, causing rotation of the abutment backwall into the backfill. In this study, a large-scale test was performed where inclined loading was applied to a 30° skewed bridge abutment with sand backfill and compared to a baseline test with uniform loading and a non-skewed abutment. The impact of rotational force on the passive resistance of the backfill and the skew adjust factor was then evaluated. It was determined that inclined loading does not have a significant effect on the passive force skew reduction factor. However, the reduction factor was somewhat higher than predicted by the proposed reduction curve from Shamsabadi and Rollins 2014. This can be explained by a reduction in the effective skew angle caused by the friction between the side walls and the back wall. The inclined loading did not change the amount of movement required to mobilize passive resistance with ultimate passive force developing for displacements equal to 3 to 6% of the wall height. The rotation of the pile cap due to inclined loading produced higher earth pressure on the obtuse side of the skew wedge, as was expected.These findings largely resolve the concern that inclined loading situations during an earthquake may render the proposed passive force skew reduction curve invalid. We suggest that the proposed reduction curve remains accurate during inclined loading and should be implemented in current codes and practices to properly account for skew angle in bridge design.

Abstract:
Skewed bridges are irregular structures due to the geometry of the deck and bents. Past earthquakes indicate that skewed bridges with seat type abutments exhibit greater damage than their non-skewed pairs. The damage has been attributed to in-plane rotations caused by pounding between the skewed deck and its abutments during strong ground shaking. This thesis combines experimental and analytical approaches to understanding the displacement demands on skewed bridges. As part of the experimental studies, results from ambient vibrations tests help to better understand the importance of directionality in the lateral response of skewed bridges. The predominant direction of the transverse response occurs in the direction of the skew bents; whereas the predominant direction of the longitudinal response is perpendicular to the skew. In addition, the analysis of records from an instrumented skewed bridge confirmed accelerations that could produce in-plane rotations of the deck. A comprehensive parametric study based on nonlinear dynamic analyses was performed to evaluate the effects of different skew angles, abutments types, and soil-foundation-structure interaction. The results demonstrated that elastic methods recommended by current seismic design provisions, and commonly used in standard practice, do not properly capture the in-plane rotations of the deck due to pounding. To overcome this shortcoming, a simple and effective method is proposed here to evaluate the displacement demands of skewed piers accounting for in-plane deck rotations. The proposed method uses validated simplified nonlinear models to generate torsional sensitivity charts for specific bridge prototypes. The charts provide peak in-plane deck rotation estimates as a function of bridge skew angle and the in-plane rotational period. An advantage of this approach is that it requires the designer to only conduct a linear dynamic analysis of the bridge. Nonlinear analysis required to assess the in-plane deck rotation is replaced here by torsional sensitivity charts. The proposed approach is able to predict the displacement response for a comprehensive range of skewed bridge prototypes by capturing the effects of the main parameters controlling the response. The information presented in this thesis will help improve the existing recommendations for performance based design of skewed bridges.

Abstract:
<p>Integral bridges are preferred by bridge authorities and road agencies because they provide a simpler form of construction, with reduced maintenance costs as a result of the elimination of bridge bearings and joints. This simpler construction brings with it design challenges as both the structure and the adjacent fill are constantly moving. Thermal expansion and contraction of the deck causes the abutments to move, leading to changes in pressure in the earth fill behind the abutment. The soil adjacent to the abutment accommodates the cyclic deck expansion and contraction caused by changes in bridge deck temperature. This results in an increase in the stiffness of the fill due to densification. Even if the fill is placed in a loose condition, it will be densified during the lifetime of the structure. The build‐up of pressure depends on the nature of the fill behind the abutment and on the type of abutment. Stiff clays show a relatively low build‐up of lateral stress however sand stresses can increase beyond at‐rest pressure and approach full passive pressures. Much of the research on this type of soil structure action has been done in the laboratory with limit conclusive field testing.</p><p>In this paper earth pressures measured over a 2 year period on a 90m long fully integral bridge are summarized and discussed in relation to measured changes in effective bridge temperature as well as the abutment movement, thus testing the hypothesis that when more strain (i.e. a longer bridge and/or increase in the change in effective bridge temperature) is imparted to the soil, more granular flow occurs, resulting not only in more rapid stress escalation, but also in higher earth pressures.</p>

Abstract:
<p>Jacobs is completing the preliminary and detailed design of two bridge replacements on County Road 17 in Ontario, Canada using an accelerated bridge construction technique known as lateral slide (also known as slide-in-bridge or jack-and-slide) for the Ontario Ministry of Transportation. The Hawkesbury Creek & CNR Overhead is a multi-span slab-on-girder structure spanning a creek and locomotive tracks. The Highway 34 Overpass is a single-span rigid frame structure spanning over the main road leading to the Town of Hawkesbury. The existing structures are approaching the end of their useful service life and rehabilitation is no longer a viable option. The new superstructures will be built on temporary supports located north of the existing structures. The new foundations consist of non-standard integral abutment details supported by composite caissons drilled through the existing roadway using temporary lane closures along County Road 17. This is an alternative to conventional integral abutment design which typically consists of a single row of steel H-piles. County Road 17 will be closed for up to four weeks to permit rapid demolition of the existing structures followed by the lateral slide. This is the first integral abutment lateral slide in the Province of Ontario. New design concepts, non-standard details and construction sequencing have been developed to achieve an economical, practical and robust design solution.</p>

Abstract:
<p>During the last five years, the north of Chile was impacted by several natural disasters not considered in the traditional code design. During 2015 a great rain fall occurred in a desert zone, it is not prepared by this amount of water, producing soil and debris currents from the mountain to the sea (about 100 km).</p><p>These phenomena produced an important damage in the infrastructure, specially focused on roads and bridges. The main damage detected was the collapse of the infrastructure (piers and abutment) and the unlinking between deck and piers.</p><p>This paper presents a proposal methodology to assess the effect of these currents on bridges, using the case of study of the Chañaral Bridge, a multi-supported bridge, with four concrete girders, slab girder and two spans of 20 meters supported in two abutments and one concrete pier, over the Charañal River.</p><p>A sensitive hydraulic analysis via FEM was carried out using non-Newtonian flows (high density) representing the real final topography-condition of the current. A FEM of the bridge was carried out too considering a Non- Linear transient load. The inputs for model are the outputs from the hydraulic model in order to define the condition that produce the same collapse behavior showed after the real debris current.</p><p>Finally, results of this methodology are discussed, providing a comprehensive methodology, step by step, in order to obtained similar results according to the 2015 event.</p>

Abstract:
<p>On April 14, 2016, an earthquake of magnitude 7.3 hit in Kumamoto Prefecture, Japan. 12 bridges were damaged and could not be restored in a short time, significantly impacting the transportation of relief supplies through emergency roads to the disaster areas. Among them, an expressway bridge supported by rocking piers collapsed, which had never occurred in past earthquakes. The collapse was caused by the failure of restraint details on an abutment. The rocking piers, however, failed to prevent the superstructure from falling subsequently, because the pier joints with the girders and pile caps were all hinges that provided no restraint to superstructure. With this collapse as a starting point, seismic strengthening of bridges with rocking piers has started being implemented all over Japan. The authors’ company launched a strengthening project in July 2017. Among the expressways under our management, the Tomei Expressway has the largest traffic volume. Any bridge falling of the expressway may cause enormous damage. This paper presents a strengthening design and construction of a bridge in the Tomei Expressway for ist rocking piers. The rocking piers were strengthened by installing braces between each two neighboring piers. In addition, based on a nonlinear dynamic analysis, the pile caps under the piers were strengthened by thickening the cross section area and rigidizing their joints with the piers using reinforced concrete, in order to provide sufficient shear and bending capacity. The pivot bearings of the piers that support the girders were also strengthened, by installing restrainers and side surface steel plates. The strengthening construction was started in August 2018 and completed in March 2019.</p>

Abstract:
<p>The application of asphaltic plug joints (APJs) for road bridges has spread worldwide. The APJ consists of polymer modified asphalt binder mixed with selective aggregates filled in the cut-out centred over the gap between bridge span ends or between the bridge deck and abutment. APJs have the advantages of being watertight and free of debris, providing a smooth seamless riding surface through the whole bridge deck for vehicles to pass over with less bump and impact. They are simple, easy, and quick to install. Nevertheless, APJs have some major disadvantages. They are soft, pliable, and weak at higher temperatures. Thus, they can deteriorate severely well in advance of their intended design life. This paper presents a new joint type, i.e. the steelframe reinforced asphaltic plug joint (SRAPJ), modified from the APJ with innovative steelframe reinforcement embedded inside it to enhance its strength and durability. The steelframe has enough vertical stiffness to match the bridge deck and enough longitudinal deformation capacity to accommodate bridge movements from thermal variations and vehicular actions. An experimental application of SRAPJs in a highway bridge and discussion on their performance are also presented. Finally, suggestion for future improvement is proposed.</p>

Abstract:
<p>The Agra-Lucknow Expressway Project extends the connectivity of the state capital with the national capital with High-Speed Corridor. The proposed expressway starts on the Agra Ring Road near village Madra, and ends on SH-40 (Lucknow – Mohan- Hasanganj – Rasulabad road) outskirts of Lucknow. A Major bridge structure of total length 90 m is built for the physical obstacles without closing the way underneath a body of water for the purpose of providing passage over the obstacle on the SAI River. The project area is covered by a deep layer of alluvium spread range from sandy to the clayey loam by the slow-moving rivers of the Ganges system. Well foundations are generally preferred in such type of strata which are prone to collapse. Since construction of well foundation is time consuming, pile foundation were proposed to complete project within time.</p><p>In this case study, the collapse of the pile bore in liquefiable soil has been observed at abutment ‘A2’of the major bridge, at scheduled chainage 265+300. The bores in pile group collapse loose clayey sandy strata. This paper discusses the reasons of bore failure and the phenomenon of actual failure at liquefiable deposits. After studying the actual failure pattern some significant remarks are find out and accordingly the new pile group arrangement is suggested. The new design considering dead load, earth pressure, superimposed dead load, Live load, wind and seismic loading is based on rivet theory. Accordingly the numbers of pile are increased in the foundation to satisfy the design requirement</p>
