SEISMIC PERFORMANCE OF SCHOOL GYMNASIA WITH STEEL ROOFS SUPPORTED BY CANTILEVERED RC WALL FRAMES
The 5th Asia Confererence on Earthquake Engineering
2014/10/16

At 2011 Tohoku Earthquake, many school gymnasia suffered damages owing to not only Tsunami but the consequent shake. One of the most typical damages observed in steel roof gymnasia supported by RC frames are failures at the anchored connections of Steel roof bearings to RC frames. Such failures were observed in not only aged structure, but recently designed gymnasia, which mean that further guideline is strongly required. However, evaluation of reaction forces at these connections is not easy because of complicated response characteristics between steel roofs and cantilevered concrete walls. In this paper, the action of cantilevered RC walls supporting steel roofs is researched using an analytical model of actual damaged gymnasium in 2011 earthquake. The obtained results are evaluated on the observed damages, and response characteristics of cantilevered RC walls are discussed, followed by proposal of easy design methods for these connections.
