摘要
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。
A beam string structure was used for the lightweight steel roofing of workers ＇ sports center of China Southern Power Grid. First,it was determined cables＇ prestress value,and then the static and dynamic analysis of the structure were carried out. The results showed that cables ＇ prestress value had a significant impact on the structure＇s static performance,and a limited impact on dynamic performance,and tilted web member could increase the rigidity and stability of the structure. Finally,the construction contents were introduced.
