Abstract
Since seismic motion of a building incorporates shape effect if the building has anisotropic shape, we should treat such shape effect for seismic response simulation of furniture. Owing to recent progress of computer devices, finite element seismic simulation of building enables us to extract particle motions at arbitrary locations in the building. The particle motion in the building is regarded as a rational input for seismic simulation of furniture in terms of integration of the shape effect. Firstly, we modeled a building having anisotropic shape, then investigated a direction of strong seismic motion by means of a lot of finite element simulations with white noise input. Finally, we performed a sesmic simulation of furniture with rational input produced by the finite element seismic simulation for the building. The seismic response of furniture naturally reflects the direction that indicates the intense seismic motion of the building and the simulation results are in good agreement with those measured by actual surveys concerning the striations caused by the earthquake.
