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.

基础材料与地震负荷下的基础或结构的相互作用可以显着改变结构的动态响应。 桩基础是广泛使用的深层基础，可以表现出明显的土壤结构相互作用。 该研究项目将考虑并将任意地震激励的选择在计算机程序中进行分析，以分析桩支持的嵌入式结构。 然后，该程序将用于研究基础系统对非垂直出现的身体波和空间不连贯的地震环境的地震反应。 研究人员和从业人员可以使用该研究项目的结果，用于设计结构的桩基础系统。
