摘要
武汉光谷国际网球中心15000座网球馆主体为钢筋混凝土框架结构,上部为可开启钢屋盖,由主次桁架、网架、可滑动钢桁架及外围的气旋组成。该结构具有建筑造型复杂、结构体系多样、需要进行高空安装等特点。针对结构体系多样和施工难度大的特点,本文采用有限元分析软件MidasGen对该钢结构屋盖的安装和卸载过程进行数值计算分析。结果表明,构件安装和卸载过程中都有可能出现最大应力,模拟分析时要考虑钢构件的安装和卸载顺序,保证结构变形、挠度和杆件应力变化均在合理范围,保证施工安全。
The main body of 15000-seat tennis courts at the Wuhan Optics Valley International Tennis Center is reinforced concrete frame,and its upper part is a retractable steel roof which is made up of primary and secondary trusses,grid frames,retractable steel trusses and peripheral cyclones.This structure has the characteristics of complex architectural design,diverse steel structure systems,and the need for high-altitude installation.In the view of diverse structural systems and construction difficulties,this paper uses the finite element analysis software Midas Gen to simulate and analyze the installation and unloading process of the steel structure roof.The results show that maximum stress may occur during the installation or unloading of components.During simulating analysis,the installation and unloading sequence of steel components should be considered to ensure that structural deformation,deflection,and stress changes of members are within a reasonable range,thereby meeting construction safety requirements.
