Seismic Evaluation of Unit Room Subjected to Ground Motion by Experimental and Numerical Studies

Abstract

In order to secure independent spaces in factories or large warehouse, unit rooms have been widely used. In Japan, large scale earthquakes occur frequently. Therefore, this study aims to review seismic design of the current unit room and propose seismic design assuming repeated ground motion. In addition, the unit room has various types and sizes according to the purpose of use. Although demand for large unit rooms has been increasing, seismic evaluation of a large unit room is difficult by experiment. Therefore, the second objective of this study is to evaluate vibration characteristics of the unit room by computer simulation using discrete element method.
