震泽中学体育场分为东、西区两个看台,东区跨度为170.7m,主骨架为梭柱斜拉索网格结构,西区跨度为224.0m,主骨架为背拉索大悬挑网格结构。采用3D3S和MIDAS软件对结构进行分析,通过控制拉索的初始预应力取值,降低整个结构用钢量。结合具体结构设计,对结构进行了静动力特性分析、屈曲分析和断索分析,同时对两种拉索网格结构的力学性能特点进行了比较和总结。
The Stadium of Zhenze Middle School divides into two grandstands in the east and the west. The span of the east zone is 170.7m. The main framework is the pylon cable lattice structure with a span of 224.0m in the west and a main cantilever large cantilevered grid structure. The 3D3S and MIDAS software are used to analyze the structure. By controlling the initial prestressing value of the cable, the amount of steel used in the whole structure can be reduced. Combined with the specific structural design, the static and dynamic characteristics, buckling analysis and broken cable analysis of the structure were carried out. The mechanical properties of the two cable structures were compared and summarized.
