中文摘要	为了计算多点输入效应对大跨弦支筒壳结构地震响应的影响程度,通过有限元软件ANSYS建立弦支筒壳结构模型,并对结构进行多遇地震下的多点输入和一致输入的时程分析,选择合理的视波速来考虑行波效应的影响,统计分析多点输入下构件最大应力、超载比例以及超载构件分布规律等情况,最终将多点地震输入响应分析与一致输入进行比较。结果表明,多点输入下设计应力比一致输入增大的构件占有很大的比例。因此,在大跨弦支筒壳结构的设计过程中,多点输入下的地震分析是必不可少的。; To study the influence of seismic response of large-span cable-supported barrel vault to multi-support excitations, the structural model was established by using the FEM software ANSYS. The time-history method was used in the structural seismic response analysis to uniform excitation and multiple excitations. The wave-passage effect was considered by selecting some reasonable apparent wave velocity. Different responses including uniform and multi-support input were compared by the parameter of the component maximum stress, overload component ratio and overload component distribution. The results show that a majority of components' design stress improve after considering the multi-support excitation effect. So the analysis of seismic response of large-span cable-supported barrel vault to multisupport excitations is essential in the structure design.
