Pile Foundations Subjected to Arbitrary Seismic Environment

在地震荷载作用下，地基材料与基础或结构的相互作用会显著改变结构的动力响应。桩基础是一种应用广泛的深基础，具有显著的土-结构相互作用效应。本研究项目将考虑任意地震激励的选择，并将其应用于桩支承嵌入结构的计算机分析程序中。然后，该程序将用于研究地基系统对非垂直入射体波和空间非相干地震环境的地震响应。研究成果可供研究人员和实践者在结构桩基体系设计中参考。

The interaction of foundation materials with the foundation or structure under earthquake loading can significantly alter the dynamic response of the structure. Pile foundations are widely used deep foundations and can exhibit significant soil-structure interaction effects. This research project will consider and implement the option of an arbitrary seismic excitation into a computer program for the analysis of pile-supported embedded structures. The program will then be used to study the seismic response of the foundation system to non-vertically incidenting body waves and to spatially incoherent seismic environments. The results of this research project can be used by researchers and practitioners in the design of pile foundation systems for structures.
