摘要]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。

Abstract: The layout of main stadium awning structure of Zhejiang Gongshang University at Xiasha Campus is crescent form, the long span is 160 m, the short span is 33.5 m, the largest cantilever is 26.2 m. It uses the cable-pipe truss composite steel structure, the whole structure mainly consists of 17 cantilever trusses, lateral trusses in the transverse front end and loop trusses at the back end, and supports on the stand concrete columns through the concretefilled steel tubular columns. Three cables are tensioned at the end of steel pipe columns which stretch outside roof, and anchor on the stand beam end through the posterior cables. Having done wind tunnel test and apply wind loads according to the characteristics that the stadium is shallow shell membrane structure and located by Qiantang River. Under comprehensive conditions, the static displacement, stress and whole structural stability were analysed with ANSYS,MSTcad and MIDAS software separately. The results satisfy the standard requirements. The concrete-filled steel tubular columns, support spherical joints, tube truss welded nodes etc were checked. Stay cables are tensioned one by one symmetrically from middle to both sides, and then the inner force were detected.
Keywords: steel-awning; cable-pipe truss; wind tunnel test; static; stability; checking calculation; tension detection
