Seismic Response Analysis of Pile-Soil Interaction in Super High-Rise Building

Abstract:

Based on the soil-structure interaction theory and finite element method, this paper analysis the seismic response of pile-soil interaction system in super high-rise building. This paper established a structure- pile-soil finite element mole of a super high-rise building in Tianjin area and analysis the dynamic response of superstructure and the internal force and displacement of the pile considering the influence of pile’s slenderness ratio. The results show that, the displacement and acceleration of the top of interaction model are increased compared with the fixed base model. Under seismic excitation, the peak displacement and the peak acceleration of pile top are larger than the pile bottom. As the pile’s slenderness ratio is larger, the inter force and displacement seismic response of the pile is larger and the variation of peak is bigger along the pile.
