“…Moreover, according to equation 22, for multi-layered or non-uniform soil conditions, there is also the difficulty of determining equivalent soil stiffness, which artificially assumes a starting value of equivalent stiffness and calculation iterations and convergence does not verify if the pile consists of different parts of different outer shapes. Although the equivalent cantilever approach is quite useful in analytical models and appropriate for evaluating the lateral strength and ductility demand of a yielding soil pile system, the full length model will be used in the following finite element model, which is capable of evaluating the pile and the structure behavior in both ultimate state and service state [98][99][100][101].…”

Bridges are one of the most critical parts of transportation networks that may suffer damages against earthquakes. Also, seismic responses of most bridges are significantly influenced by soil-structure interaction effects. Taking out expansion joints in the bridges may cause many difficulties in design and analysis due to the complexity of soil-structure interaction and nonlinear behavior. The secondary loads on an IAB include seismic load, temperature variation, creep, shrinkage, backfill pressure on back wall and abutment, all of which cause superstructure length and stress variations in girder changes. The purpose of this study is to recognize the most effective parameters of analysis IABs. Findings show that the backfill material behind the IABs has a significant effect on the performance of IABs. Using a compressible material behind the abutments would enhance the in-service performance of IABs. Finally, behaviour of abutment may be greatly affected by thermal load and soil pressure. Thermal expansion coefficient significantly influences girder axial force, girder bending moment, and pile head/abutment displacement.
