Construction of high-fidelity finite element model for large-scale parallel seismic analysis of Soil-underground structure

抄録

Development of E-Simulator, which aims at reproducing the damage/collapse mechanism of soil, bridge and building structures against strong earthquakes, is a project of E-Defense. Data measured in E-Defense shake table tests are used for validation of E-Simulator. As a research subject in the field of soil structures, we aim to simulate the large-scale experiment of soil and underground structures conducted at E-Defense in February 2012. In this study, we conduct elastic analysis by using detailed solid model of soil and underground structures. Our main objectives of this research are to determine the suitable mesh of analysis model and to identify appropriate technique to impose lateral boundary condition. Then, we clarify how the detailed solid model can simulate the experimental result and the limitation of the elastic analysis and identify the issues to be taken care of in the elasto-plastic analysis.
