| Research Abstract |
Rocking type precast-concrete cartain walls were usually used for high-rise steel buildings. Loading tests were conducted to simulate behavior of PCa panel accommodate to 1/5 – 1/3 inter-story drift of building structures. It is found that in case of in-plane direction story-drift, the panel failed by collision at the corner due to the failure of fastener of the panel, and in case of out-of-plane direction story-drift, the fastener deformed and the panel accommodate to the drift. The calculation methods of the behavior of panels are presented and those validity is verified by results of loading tests. The methods to evaluate the limit of accommodation and the post-limit behavior are presented and the useful information to prevent the fall of panels are obtained.
