摘　　要：摩擦摆支座是一种有效的摩擦滑移隔震支座,其特有的圆弧滑动面具有自动复位功能,既可以有效减小隔震支座的位移,又可以在水平作用力消失后恢复原位。论文通过工程实例,采用SAP2000及MSC.MARC软件计算分析了高层顶部连接体钢棚架在三向地震作用下的摩擦摆隔震结构的地震反应,同时,与钢结构连接体棚架的常规固定铰支座的地震反应进行了对比分析。The friction pendulum bearing is an effective friction slide isolation bearing,and its unique circular sliding surface has the function of automatic resetting,which can not only effectively reduce the displacement of the isolation bearing,but also restore the original position after the disappearance of the horizontal force.Based on an engineering example,SAP2000 and MSC.MARC software were used to calculate and analyze the seismic response of the friction shimmy isolated structure of the steel frame with top connector in the high-rise under the action of three-way earthquake.At the same time,the seismic response of the conventional fixed hinged supports of the steel frame is compared and analyzed.
