| 摘 要： | 非规则结构隔震层在平扭耦联地震中会产生平动与转动.隔震支座则处于水平双向受剪状态.文章设计了一种加力装置使直径100mm的单个铅芯橡胶隔震支座产生两个水平方向的变形,相应隔震层则产生平动和转动.通过两种布置工况对隔震支座进行两种水平加载比例的双向低周疲劳试验,得到了橡胶支座水平Y向滞回曲线以及扭矩与隔震层转角的关系.试...

| Abstract: | Under the translation-torsion coupling earthquake action,translation and torsion motion of corresponding isolation layer occurs,and lead rubber bearing is under two-dimensional shear.This paper designs a two-dimensional strength device,which could test 100 mm lead rubber bearing under two-dimensional shear.Translation and torsion motion of corresponding isolation layer also occurs.Through two decorate conditions,LRB under low cycle fatigue loading of two horizontal proportion is tested.The relation between ... |
