南方电网职工文体活动中心轻钢屋面采用张弦梁结构。首先,确定了拉索预应力取值,在此基础上对结构进行静力和动力分析,表明拉索预应力对结构静力性能影响显著,对结构动力性能影响有限,而斜腹杆的存在增加了结构的刚度和稳定性。最后,对有关施工内容进行了介绍。 CSG staff sports center light steel roof structure using beam string. Firstly, the value of cable prestress is determined. Based on the analysis, the static and dynamic analysis of the structure is carried out, which shows that the cable prestress has a significant effect on the static performance of the structure and has a limited impact on the dynamic performance of the structure. However, Increased structural rigidity and stability. Finally, the construction content is introduced.
