Abstract
This paper presents a study on seismic soil–pile installation using numerical modeling in conjunction with centrifuge model studies. The numerical analyses were conducted using ABAQUS with a hypoelastic constitutive model for the clay. Numerical analyses were used to extend the range of soil, pile, and ground motion parameters which could not be studied in centrifuge. The dimensionless parameters involving the major parameters such as pile modulus, soil modulus, slenderness ratio, natural frequencies of clay layer and pile-raft, superstructure mass, density of the soil and peak ground acceleration were obtained from the parametric studies. The relationships for the amplification of ground motions and the maximum bending moment in the pile were developed based on regression of the numerical data.
