摘　　要：针对单层平面索网幕墙结构的特点,构造了非线性单质点体系,利用多条地震动记录,采用时程分析方法计算了该类结构在小震、中震和大震下的加速度反应谱。在此基础上,经过统计、平滑处理,得到了适用于单层平面索网玻璃幕墙结构抗震设计的设计地震反应谱和地震影响系数。Research has been rarely focused on the seismis performance of the plane single-lager cable net supported glass curtain structure. The nonlinear single degree of freedom（SDOF）of the structure is proposed. The nonlinear acceleration spectrums are calculated under given conditions and different seismic intensity with time-history analysis method using many ground motion records. The acceleration response spectrums, average acceleration response spectrums and statistic smoothing design aseismic response spectrums are developed.
