摘　　要：索桁预应力穹顶结构是一种新型的空间结构形式.本文针对这一特定的结构形式,通过改变结构参数(矢高、预应力、布索方式),得出其相应的静动力特性的变化规律,从而探明了结构的参数变化对其静动力特性的影响,得到一些有参考价值的结论.The cabletruss prestressed dome structure is a new type of spatial structure.In this paper a given structure of this type was analyzed and the corresponding change ways of its dynamic and static properties were investigated by modifying the parameters including the risespan ratios,prestress and cable distributions.The influcence of structure's parameters on the dynamic and static properties of the structure were also determined.Some useful conclusions were obtained.
