Computer Simulation on Dynamic Soil-Pile-Superstructure Interaction System Considering Liquefiable Foundation
Abstract eng: A three-dimensional numerical analysis of shaking table tests on dynamic soil-pile-superstructure interaction (SSI) system considering soil liquefaction is presented in this paper. The finite difference method FLAC3D is used in the analysis. A 12-story reinforcement concrete frame structure is employed to simulate the superstructure. Nonlinearity of the soil and pore water pressure build-up process, and the interface behavior between piles and surrounding soil under seismic input is taken into account in the model. With the established model, variation process of dynamic pore water pressure of the soil is discussed and some important findings are obtained. By comparing the results of the numerical analysis with the data from shaking table tests, the computational model is validated.
