摘　　要：将摩擦摆支座(FPS)应用于单层球面网壳结构的隔震,给出了隔震网壳结构的运动方程。通过对比分析不同强度地震动输入条件下的结构动力响应特征,考察了FPS支座应用于网壳结构隔震的有效性和适用性。研究结果表明,在不同强度的地震动作用下,隔震结构的节点加速度峰值和杆件轴力峰值都得到了有效控制,且地震动强度越大,控制效果越好。Friction Pendulum System （FPS） is applied to single-layer spherical lattice shells to investigate its seismic isolation performance. The governing equations for the structure with FPS are developed. The effectiveness of the FPS is examined by analyzing the characteristics of seismic responses, which are induced by different intensity of ground motions. It is shown that nodal acceleration and element axial forces of the structure are effectively mitigated. Meanwhile, the isolation effectiveness is going to be better under intenser ground motions.
