Seismic Performance Evaluation for Wall-Type Precast Concrete Housings Using CRLS

Abstract eng:
The purpose of this study is to construct the seismic performance evaluation method for the wall-type concrete panel housings using the Calculation of Response and Limit Strength (CRLS), which is a new performance -based structural evaluation method for buildings introduced in 2000 in the Building Standard Law of Japan (BSL). The housing is one of low-rise prefabricated housings of the wall-type that precast reinforced concrete (RC) panel members with ribs, assembled by steel bolts. The BSL revised in 1998 stipulated to carry out the structural calculations using the CRLS for this type of RC buildings which use thin walls less than 120mm in thickness. In order to evaluate the seismic performance of the wall-type housings using the CRLS, analytical member models to be used for the pushover analysis of the housings were constructed based on the structural testing in this study. The results of pushover analysis using member modeling based on structural component tests were compared with the experimental results of a two-story full-scale wall-type housing tested in 1981 to verify the prediction accuracy. Moreover, the seismic performance evaluation using the CRLS for real wall-type concrete panel housing was executed.
