THREE-DIMENSIONAL ANALYSIS FOR THE EFFECT OF PILES GEOMETRY AND ARRANGEMENT ON THE DYNAMIC RESPONSE OF PILED RAFT FOUNDATION

In the present study, three-dimensional analysis is presented to investigate the effect of pile dimensions and configuration on the dynamic response of piled raft foundations subjected to vertical vibration. The analysis considered several factors affecting the maximum amplitude of vertical displac...

description In the present study, three-dimensional analysis is presented to investigate the effect of pile dimensions and configuration on the dynamic response of piled raft foundations subjected to vertical vibration. The analysis considered several factors affecting the maximum amplitude of vertical displacement of deep foundation such as length, diameter, number of piles, and spacing between piles. Furthermore, a validation for experimental piled raft models depending on a scale factor of (20) using (Plaxis 3D) computer software is presented. The sand is simulated using the (mohr-coloumb) model, while the concrete is simulated as a linear elastic material. It has been found that the increasing length and diameter of piles lead to a decrease in the maximum amplitude of displacement. On the other hand, the results showed that the increasing number of piles and increasing the spacing between piles can minimize the dynamic response of the foundation.
