浙江工商大学下沙校区主体育场钢屋盖罩棚结构平面布置呈月牙形,其中长向160m,短向33.5m,最大悬挑26.2m,采用拉索-管桁架组合结构,整个结构主要由纵向17榀悬挑桁架及横向前端的横桁架和后端的环桁架组成,并通过钢管混凝土柱支承在看台结构的混凝土柱上。在每根伸出屋面的钢管柱顶斜拉三根拉索,并通过后索锚固在看台的梁端部。针对结构为扁壳膜结构并地处钱塘江边的特点进行风洞试验,并据此施加风荷载;利用MSTcad及ANSYS软件联合进行综合工况静力分析,得出的结构位移、应力等均满足要求;利用MIDAS软件进行结构整体稳定性分析,满足规范要求。对钢管混凝土柱、支座球节点、管桁相贯节点等进行验算;拉索张拉从中间向两边逐根对称进行,并对其进行检测。
Zhejiang Gongshang University Xiasha campus main stadium steel roof cover shed structure layout was crescent-shaped, of which 160m long, short 33.5m, the maximum cantilevered 26.2m, the use of cable - pipe truss combination structure, the entire structure mainly by the longitudinal 17 榀Cantilevered truss and the horizontal front transverse truss and the rear end of the truss, and through the concrete-filled steel column column structure in the concrete column. Three cables are inclined at the top of each steel pipe column protruding from the roof, and are anchored to the beam ends of the stands by the rear cables. The wind tunnel test was carried out for the structure with a flat shell membrane structure and the Qiantang River, and the wind load was applied accordingly. The static analysis of the comprehensive working condition by MSTcad and ANSYS software was conducted to meet the requirements of structural displacement and stress ; Using MIDAS software to analyze the overall structural stability to meet regulatory requirements. The concrete-filled steel tubular columns, the bearing ball joints and the joints of the pipe trusses were checked. The tension of the tension cables was symmetrically carried out from the middle to the two sides, and its detection was carried out.
