“…maximum length and skew angle limits), pile types and orientations, abutment design, wing-wall configuration and abutment-backfill interaction in IABs especially under thermal and seismic loading. Moreover, many research studies have been conducted on the effect of backfill and foundation soil on the performance of IABs under thermal effects [15][16][17][18][19][20][21]. However, research studies concerning the effect of soil-bridge interaction on the performance of IABs under live loads are scarce.…”

“…It was observed that proper compaction of backfill soil behind the abutment influenced the axial force and bending moment in the superstructure bridge deck. Soil-pile interaction of these bridges was also investigated by using solid continuum elements to model soil and pile members [8]. The loads on the piles imposed by superstructure were found to affect a small volume of soil around the piles.…”

Soil-structure interaction results in a significant modification of structural behavior, which in turn affects its seismic response. Most of the current structural analysis methods, prescribed by the design guidelines of different countries, do not account for it. The necessity of incorporating soil-structure interaction in the investigation of a wide range of bridge structures has been pointed out by several post-earthquake investigations and experimental and analytical studies.The current study is focused on the effect of soil-structure interaction on the seismic behavior of reinforced concrete (RC) piers of an integral bridge. First, a symmetric long-span RC bridge with fixed base is modeled using the computer program OpenSees. Next, the soil domain, along with the absorbing boundary conditions, is modeled in GID preprocessor program, and the bridge and soil domains are combined. Two types of scaled ground motions of different characteristics, namely, broadband and narrowband, are applied at the base of bridge, and the response of structure is studied by linear time history analysis. The forces at critical sections and displacement response are obtained.The same bridge with fixed base is modeled in the program SAP2000, and response spectrum analysis is carried out to find the design response of structure. The design response obtained from SAP2000 model is compared with results obtained from the model using OpenSees. It is observed that the design code overestimates the possible response significantly.

“…There are some theories and correlations for calculation of soil lateral pressure that were proposed in the past researches. Some coefficients were defined just as functions of soil properties like in Coulomb's and Rankin's theories while in others such as British Standard, Massachussetts manual, Canadian manual and Hussein and Bagnaroil, they were proposed either as functions of soil properties or abutment wall displacement (Khodair and Hassiotis, 2005). Figure 2 shows the distributions of soil lateral coefficient and earth pressure along the abutment height (Abendroth and Greimann, 2005).…”

Problem statement: In this study, the behavior of abutment wall in full height frame integral abutment bridges was investigated. It was seen that the effect of backfill soil resistance on behavior of abutment wall movement is mostly neglected in previous studies. In this research, the final bridge superstructure displacement under temperature-induced forces was formulated. In addition, according to the final bridge displacement, the earth pressure that acts as a resistant force on the bridge abutment using the new equation from British design manual for roads and bridges, BA 42/96 was used. Besides, in the construction of integral bridges, the deck and girders are mostly encased into abutment wall, which makes these bridge components as fixed elements. This fix connectivity makes the top abutment wall move along with the bridge deck. Moreover, the abutment wall in integral bridges is made of reinforced concrete and thus, it could be assumed as a rigid mass that has a linear deformation behavior. Approach: To implement a new method to calculate the amount of abutment wall movement at different elevations in full height frame abutment integral bridges, considering the parameters such as temperature changes, bridge deck elongation and the backfill soil resistance. First, internal forces of the bridge abutment were formulated. They were all presented as functions of bridge deck final displacement. Second, different methods to calculate the soil lateral pressure were used. Third, the numerical modeling was applied and the corresponding results due to the bridge deck elongation were extracted. Fourth, the results obtained from phases two and three were compared to obtain some conclusion. Results: The results derived in this study, consisted of four data sets. First, the existing forces such as the bridge deck elongation force, the backfill soil resistance etc. were formulated according to the bridge final displacement. Then after, the static principals revealed the amount of deck final elongation. For the second set, different correlations such as British Standard, Massachusetts manual and etc. which had considered the effect of deck final displacement in their formulas were presented and with regard to the first part, the backfill reactions were obtained. For the third set, by combining the results from set one and two, different values for the deck final displacement were derived. For the next step, according to the fix connectivity of the abutment and the bridge deck, the abutment top elevation displacement was set equal to the deck final displacement. For the bottom elevation, because of the rigidity of the wall and the rotational behavior about its foundation, the displacement was set zero. Therefore, by assuming linear deformation behavior of rigid masses, the abutment deformation profile for different elevations was concluded. For the last set, the bridge computer model was built using SAP2000 and the corresponding results were collected. Conclusion: It was seen that, generally, except for some certai...
