The objective of this research program is to investigate the effects of nonlinear soil behavior on the response of soil- structure systems to earthquake loading. The project involves: (a) the development of a numerical model to represent the various phenomena to be studied, such as the mechanical response of the soil and nonreflecting boundary conditions; (b) validation of the model by first comparing the predictions of the linear component of the model against closed- form analytical solutions for simplified systems, then by introducing nonlinearities into these simplified systems; and (c) following calibration of the numerical model, use of this model to analyze and interpret the data for a scaled-down nuclear containment vessel in Lotung, Taiwan, where soil nonlinearities and soil-structure interaction effects are dominant. This component is jointly sponsored by the Electric Power Research Institute (EPRI).

该研究计划的目的是研究非线性土壤行为对土壤结构系统对地震负荷的响应的影响。 该项目涉及：（a）代表要研究的各种现象的数值模型的发展，例如土壤的机械响应和非反射边界条件； （b）通过首先将模型的线性组件的预测与简化系统的闭合形式的分析解决方案进行比较，然后通过将非线性引入这些简化的系统来验证模型； （c）在校准数值模型后，使用该模型来分析和解释台湾Lotung缩小的核遏制容器的数据，在那里土壤非线性和土壤结构相互作用效应是主要的。 该组件由电力研究所（EPRI）共同赞助。
