摘　　要：现代建筑由于规模的扩大,建筑过程的漫长多变,需要对施工期间不完整的建筑结构的受力性能进行研究。文中着重研究新型轮辐式张弦梁的施工过程,通过建立多种不同的张拉方案,对其索力进行分析,以便寻得最优张拉方案。运用非线性有限元理论,对某体育馆新型轮辐式张弦梁结构进行施工仿真分析研究,通过ANSYS对新型轮辐式张弦梁索的张拉过程进行模拟,主要探究采用不同的张拉顺序对受力性能的影响。最终得出不同的张拉方案只会改变中间过程的索力值,对最终结果没有影响。Due to the expansion of the scale of modern buildings as well as the long and changeable construction process,it is necessary to study the mechanical properties of incomplete building structures during construction.This paper focuses on the construction process of the new spoke beam string.By establishing various tension schemes,the cable forces are analyzed in order to find the optimal tension scheme.In this paper,the construction simulation analysis of a new type of spoke beam string structure in a gymnasium is carried out by using the theory of non-linear finite element.The tension process of the new type of spoke beam string cable is simulated by ANSYS,and the effect of different tension sequence on the mechanical performance is mainly explored.Finally,different tension schemes can only change the cable force in the intermediate process,and have no effect on final results.
