Abstract
In this study, the limit curve relating between energy absorption and maximum displacement is derived from cyclic loading test of wood shear walls. Time-history analysis is also conducted to evaluate safety of wood shear wall based on the limit curve. As the results, following conclusions are obtained:
1) Limit state derived from energy absorption and maximum displacement of wood shear wall is similar to that of steel members. That means limit state is determined by energy absorption index.
2) The state mentioning above is slightly different from types of shear wall. Characteristic of sheathed shear wall such as plywood shear wall is close to steel member but that of bracing shear wall is close to medium characteristic of steel and reinforced concrete member.
3) According to results of time history analysis, responses which are designed in accordance with minimum requirement of Japanese building standard law transcend the limit state during extremely big earthquakes such as JMA Kobe and JMA Kawaguchi.
4) Aftershock should be considered in seismic performance for shear walls which is sensitive to energy absorption.
