在2011年东北地震和2016年熊本地震中，钢筋混凝土体育馆的许多钢屋顶轴承遭到破坏，主要是由于悬臂式钢筋混凝土墙的面外响应。虽然作者证实了摩擦阻尼支座对悬臂RC墙的纵向响应减小作用，但没有对横向响应进行研究。本文对四氟板滑动轴承、摩擦阻尼轴承和橡胶板轴承进行了动加载试验。利用试验结果构成的支座滞回线，对剪力墙纵向和横向的响应进行了数值模拟计算。
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.
