A STUDY ON ESTIMATION METHOD OF SEISMIC RESPONSE BEHAVIOR OF BASE-ISOLATED WOODEN HOUSE BASED ON FULL SCALE VIBRATION TESTS

摘要

In this paper, based on vibration test of a conventional wooden house with base-isolation devices that were newly developed for light-weight building, base-isolation efficiencies of specimen and seismic behavior characteristics of slide-type base-isolated building were examined. The leading results are as follows. 1) The specimen has enough base-isolation efficiency. 2) Vertical seismic motion has almost no effect to horizontal response displacement. 3) Maximum response displacement under two-way seismic motion nearly agrees with that under one-way seismic motion on principal axis of input velocity.
