Abstract

A three-dimensional nonlinear finite element procedure is presented for analysis of drilled (concrete) piers. The procedure allows for tensile cracking and compressive crushing of concrete, nonlinear behavior of soil, and simultaneous application of axial and lateral loads. The procedure is employed to investigate the ultimate capacity of a 45° under reamed pier. The predicted results are compared with the field test conducted on a similar pier. Also, distribution of displacements and stresses in the soil-pier system and crack pattern in the pier are presented and discussed.

Simulation of Drilled Pier Behavior under Three-Dimensional Loading

A three-dimensional nonlinear finite element procedure is presented for analysis of drilled (concrete) piers. The procedure allows for tensile cracking and compressive crushing of concrete, nonlinear behavior of soil, and simultaneous application of axial and lateral loads. The procedure is employed to investigate the ultimate capacity of a 45° under reamed pier. The predicted results are compared with the field test conducted on a similar pier. Also, distribution of displacements and stresses in the soil-pier system and crack pattern in the pier are presented and discussed.
