Abstract: To study the isolation situation of the friction pendulum foundation sliding isolation frame structure, the theory of the friction pendulum system was a basis and the multi-storey reinforced concrete frame structure was selected. The finite element software SAP2000 was used to modeling, the definition of operating conditions, model analysis and data extraction. To analyze the damping effect, seismic response of isolated structures was analyzed and compared with that of fixed base structures, such as the natural period, the floor maximum acceleration response, displacement between floors and interlayer shear forces. Analysis results indicate that a reasonable parameters set of the isolation layer, formula and program analysis results agrees well with each other. The FPS technology has obviously damping effect and it can decrease the maximum response of structure sharply when earthquake occurs, including the natural period, acceleration response, the layer displacement and interlayer shear. Some of the damping rate even exceed 90%.

摘要： 为研究摩擦摆基础滑移隔震框架结构的隔震情况，以摩擦摆系统的理论为基础，选取多层钢筋混凝土框架结构为研究对象，采用有限元软件SAP 2000进行模型建立、工况定义、模型分析和数据提取。比较基础固定结构和基础滑移隔震结构在地震作用下的反应特性，如自振周期、楼层最大加速度反应、层间位移、层间剪力，分析其减震效果。研究结果表明: 合理设置隔震层的参数，公式计算结果与程序分析结果吻合较好，摩擦摆隔震系统具有明显的减震效果，大大降低地震作用下的结构的峰值反应包括自振周期、加速度反应、层间位移和层间剪力，某些减震率甚至超过90 %.
