| 摘 要： | 为了研究大跨度张弦桁架结构的静力特性和自振特性,以镇江体育中心会展馆为研究对象,采用ANSYS有限元软件,对镇江体育馆整体空间结构进行了相应的计算分析,静力进行分析,研究了不同预应力、拉索横截面积对其静力性能的影响,结果表明,张弦桁架结构的预应力、拉索横截面积对结构的静力性能影响很大;然后分析了竖向支柱的有无对张弦结构振型、频率的影响,分析表明,有竖向支柱对结构振型和频率的影响很大。 |

| Abstract: | In order to study the static and self-vibration characteristics of the long-span truss string structures,and based on Center Exhibition Hall of Zhenjiang Sports,ANSYS is used to make the corresponding calculation and static analysis on the overall spatial structure of Sports Hall,and the influence of different prestress and lasso’s cross-sectional area on the static performance is also analyzed.The result shows that the prestress and the cross-sectional area greatly influence the composition’s static performance.Then the paper further studies if the vertical columns influence the truss structure’s vibration model and frequency,the result shows that the vertical columns greatly influence the vibration model and frequency. |
