Parametric study of pile cap lateral resistance: finite element analysis

Abstract Analytical studies using finite element analysis of pile cap resistance under lateral load is seldom reported in literature. Recently, presents the results of experimental study on model piles to show the effect of pile cap elevation below the ground surface and pile spacing on lateral resistance of single pile and pile groups driven in sand. From their parametric study, they concluded that the lateral carrying capacity of single pile and pile groups increase as the pile cap depth below the ground surface increases and as the spacing between piles in the group increases. The objective of this study is to study pile–soil–cap interaction under lateral load considering different influences parameter and thus quantifying the lateral resistance for different conditions. Finite element modeling and analysis is performed for three different spacings, namely 3D, 5D, and 9D for RCC pile with 300, 400, and 500 mm diameter. It is observed that pile cap has lateral resistance varying from 35·42 to 44·06% implies good agreement with the findings of .
