摘　　要：采用可考虑行波效应和部分相干效应的人工合成多点地震动,同时考虑网壳结构的材料非线性和几何非线性,对柱壳在多点输入下的地震反应进行计算,并与一致输入下的地震反应进行对比,考察二者之间的差异;深入分析了大跨度单层柱面网壳结构在多点输入下的地震反应规律,得出一些有益于工程实际的重要结论.In this paper, simulated ground motions are produced with consideration of incoherent effect and wave-passage effect. Based on both geometrical nonlinearity and material nonlinearity, seismic response of long-span single layer cylindrical reticulated shell under multi-support excitations and uniform excitations is studied, and comparison is also made. Profound analysis is made of the rule of seismic response of reticulated shell under multi-support excitations, and some important conclusions are drawn.
