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 cabletruss 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 risespan 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.
