| 摘 要： | 在综合Spacone关于梁柱的纤维模型和铅芯橡胶隔震支座剪切变形特点的基础上，提出了采用纤维单元有限元模型来分析隔震支座在竖向和横向荷载作用下的滞回模型．结果表明，采用纤维单元模型的模拟结果与试验曲线基本吻合，它既可用于分析隔震支座的基本参数，也可用于隔震建筑的动力响应分析．

| Abstract: | According to Spacone beam column fiber model and shear deformation of leader rubber laminated bearings, a fiber element model is presented to simulate the hysteretic loops of lead rubber bearings in a lateral cyclic shear under a compressive axial load. This result shows very small difference between the analytical hysteretic loop and the experimental hysteretic loop. Thus, the proposed model not only can predict the force displacement curve of bearings, but also can be used to analyze dynamic response of base isolated building. |
