Numerical Modeling of a Dynamic Pile–Soil Interaction in Layered Soil Media

Due to use of pile foundations for important structures such as tall chimneys, television towers, high rise buildings, high retaining walls, offshore structures, safe and economic design of types of foundations under dynamic loading is especially important. First of all, it is necessary to investigated complexity of the issues related to the behavior of pile and pile-soil interaction evaluated the effects of the earthquake and methods of foundations analysis. Interactions between the components of the piled raft foundation have a significant influence on the analysis. Therefore, the interaction effects have been fully considered. ABAQUS 6.10 software has been used for analysis models. The models have been calibrated against available certified models. Researchers have rarely studied the effects of seismic stations for piled raft foundations. To get comparable results, the accelerograms have been scaled before performance of the piled raft foundation studied in two layers of soil media. The effect of raft foundation thickness, length, and diameter of the piles have been studied under the Bam earthquake accelerograms in the three of seismic stations. The results show that maximum and differential settlement decreases and moment is transferred to the cap pile increase when increase raft thickness.
