摘　　要：为了探明预应力对复杂空间结构受力性能的改善程度,以沈阳艺术中心音乐厅结构工程为研究对象,分别建立了预应力混凝土结构和普通钢筋混凝土结构整体有限元模型,在结构自重作用下对比分析了两种结构模型的变形和内力。结果表明在结构中设置预应力可以大大提高结构的刚度,变形最大减少62%,内力减少85%。In order to study on effect of prestress arrangement on mechanical behavior of complex space structure, these two FEM models which are based on the practical concert hall structure of Shenyang culture ＆ Art Center are made under dead load. One FEM model is prestress structure, the other FEM model is reinforced concrete structure. These analyses are carried out using finite element package Midas GEN, in this paper. In these analyses, compare results of deformation and internal force between the two FEM models. From these results, it is found that prestress arrangement improves stillness of structure, maximum deformation decrease 62%, internal force decrease 85%.
