000021622 520__ $$2eng$$aA more sophisticated analysis is being required to examine the seismic safety of an important structure subjected to larger ground motion. The utilization of high performance computing (HPC) is a key issue to realize such an analysis. This study is aimed at developing a non-linear finite element method (FEM) that uses HPC to analyze large scale problems of a soil-structure system. The developed FEM has the following four key features: 1) the implementation of non-linear constitutive relations of soil and concrete; 2) the automated construction of model of high fidelity; 3) an efficient treatment of virtual boundary conditions; and 4) initiation and propagation of multiple cracking in materials and interfaces. A methodology of constructing a simplified but consistent model (such as a stick model) from an FEM model of high fidelity is also proposed. Presented is an example of numerical experiments that uses the developed FEM for the seismic response analysis of an actual structure.
