Development of Extremely Large-Scale Analysis Software ( E-Simulator: Virtual Shaking Table) for Earthquake Dynamic Collapse Analysis of Structures

Abstract eng:
This report presents a research project of developing “E-Simulator: virtual shaking table”, which is a simulation software based on a finite element method to analyze non-linear seismic response of constructions, as a part of E-Defense project. The key features of E-Simulator are 1) extremely large-scale numerical computation that realizes the finest temporal and spatial resolution of the structure response and 2) simulation of collapsing processes of structures that is comparable with the 3D full-scale model earthquake tests of E-Defense. This report explains the objectives of the E-Simulator and its two features. It also introduces the current state of E-Simulator project which includes the earthquake dynamic collapse analysis of 31-story steel framed structure and particle discretization scheme FEM for the RC structure.
