The subject of this article is to see if a spatial variation of horizontal to vertical spectral ratios (HVSRs) of microtremors can be regarded as a proxy of an irregulari [...]

Dynamic soil-structure interaction largely affects the seismic performance of building structures in many cases. It is effective to measure real behaviors of a building a [...]

This paper reports the results of investigations into the cast-in-place reinforced concrete piles of an 8-story steel reinforced concrete structure that were damaged by t [...]

Seismic isolation is one of very effective ways to mitigate damages to building/houses caused by earthquakes. However, the application is still limited to specific buildi [...]

The main building of the National Museum of Western Art (NMWA), Japan, is a historic building completed in 1959. To improve the seismic performance of the NMWA main build [...]

Recently earthquake ground motions with large amplitude and/or long period component act on seismically isolated buildings. In case of family houses, responses of isolate [...]
