STRUCTURAL ANALYSIS OF A TIMBER MAIN HALL OF A TEMPLE BEFORE AND AFTER BASE-ISOLATED RETROFIT

Abstract

It is well known that timber buildings often suffer damages under maximum earthquakes and some problems of existing non-conformity buildings in Japan have to be solved. In this paper, we choose a certain temple in Tokyo, for which a base-isolated retrofit is constructed, to reveal its own structural properties. We make seismic diagnoses including limit strength calculations. We also conduct micro-tremor measurements and earthquake response analyses.
