SEISMIC RESPONSE EVALUATION AND DESIGN METHOD OF STEEL ROOF BEARINGS IN SCHOOL GYMNASIA WITH CANTILEVERED RC WALL FRAMES

Abstract

In the 2011 Tohoku Earthquake, a large number of school gymnasia suffered damage. One of the most typical damage observed in steel roof gymnasia supported by the RC frame is failure at the anchored connections of steel roof bearings on the RC frame. In this paper, the practical evaluation methods that we proposed in our past papers, of the reaction forces at the anchor connections, of the displacements at the roller bearings, and of the design requirements for the friction dampers, are compared with the time history analysis results.
