In recent years, the Institution of the Long-Life quality housing for Wooden structure house is needed proper maintenance and evaluation of seismic performance. And the application of the vibration control structure for Wooden structure is also increasing. In order to evaluate seismic performance of wooden structure directly, it is useful that time-history earthquake response analysis is useful to evaluate the response about input energy of earthquake. In this report, we analyzed damping of wooden structure from the measured vibration data, and propose the damping model for Wooden structure. We compare response analytical result with experiment.

In order to understand the response of strong motion at the ground landfill in Tokyo Bay area, we conducted a seismic response analysis of a wide area. The area is a reclaimed land in Tokyo Bay, and it was modeled by three-dimensional FEM over 100m depth 8km north-south east-west 10km. Alluvium was expressed by the non-linear model. In the results of the displacement distribution and acceleration distribution, we found that there is a strong correlation with the alluvium base contour and buried valley.
