摘　　要：本文详细地研究了夹层橡胶隔震垫（ 铅芯与非铅芯） 的回转刚性， 给出了回转刚性与竖向压力及剪切变形的相关性能。文中同时还研究了橡胶垫在以恒定或变化回转角度发生剪切变形时的力学性能（ 含刚度及阻尼性能） 的变化规律。试验研究结果表明， 在采用柱端隔震时， 夹层橡胶隔震垫（ 铅芯与非铅芯）The rotational stiffness of rubber bearings(RB) and lead rubber bearings(LRB) is researched firstly. The vertical compression and shear deformation dependence for mechanic characteristics of RB and LRB are provided too in the paper In our research, we complete the test in order to understand the mechanic characteristics of both RB and LRB with fixed or unfixed rotation in fivedifferent cases It is possible to use the column top isolation system (CTIS) on existing building or new building according to the test results, which show that both RB and LRB have stable properties when shear deformation is more than 30%
