Depending on the numerical accuracy required, we can choose a simple mass spring system or a solid element model in carrying out structural seismic response analysis. The [...]

In order to make a practical disaster assessment based on simulations, we need detailed urban models, which include all individual buildings in a target city. However, th [...]

A more sophisticated analysis is being required to examine the seismic safety of an important structure subjected to larger ground motion. The utilization of high perform [...]

Integrated earthquake simulation (IES) is a seamless simulation of analyzing the seismic wave propagation process and the structural seismic response process. A model of [...]

The 2011 Great East Japan Earthquake exposed limitations of present hazard maps and evacuation manual for unexpected earthquake and tsunami. In particular, information fo [...]

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 [...]

In the Tokyo metropolitan area, long tunnels are being constructed to make a ring road network. These long tunnels need a ramp tunnel which connects the main tunnel locat [...]
