Abstract

Numerous steel roof bearings in RC gymnasia were damaged at the 2011 Tohoku and 2016 Kumamoto Earthquake, mainly due to the out-of-plane response of cantilevered RC walls. Although the authors confirmed the longitudinal response reduction effect of the cantilevered RC walls by friction damper bearings, the transverse response was not examined. In this paper, dynamic loading tests of a sliding bearing with PTFE sheets, a friction damper bearing, and a rubber sheet bearing are conducted. The response of the RC walls in the longitudinal and traverse direction is calculated by numerical simulation using bearing hysteresis loops constituted by test results.
