The Nankai Trough earthquakes which are subduction earthquakes with magnitude greater than 8 have occurred at intervals of 90 to 150 years. The probability of earthquake [...]

Recently, the possibility that a high-rise building generates the vibration with large displacement amplitude against the long-period earthquake ground motions by the oce [...]

For expanding microtremor survey techniques to make it possible to estimate the irregular subsurface structure in sedimentary basins, the behavior of the H/V spectra and [...]

High-rise buildings in mega-cities such as Osaka and Nagoya in Japan have a high probability of damage due to strong long-period ground motions from a great subduction ea [...]

This research focuses on the nonstructural components in high-rise buildings subjected to large seismic responses. A serious of large-scale shaking table tests is conduct [...]
