The Stochastic Dynamic Reliability Research on Nonlinear Pile-Soil-Structure Interaction System with Uncertain Parameters
According to the damage characteristics of pile-soil-structure interaction system subjected to the earthquake, the seismic design method of using the dual design guideline of strength and deformation and taking the same reliability for both pile foundation and superstructure was put forward. The stochastic dynamic reliability of pile-soil-structure interaction system with uncertain parameters was studied on the basis of the randomness of earthquake, the nonlinearity of soil material parameters, and especailly the variability of soil material parameters. The results show that the control indexes of pile foundation and superstructure decreases with the increases of failure probability and the variation of material parameters will make the pile foundation structure partial unsafe.
