［摘要］浙江工商大學(xué)下沙校區(qū)主體育場(chǎng)鋼屋蓋罩棚結(jié)構(gòu)平面布置呈月牙形，其中長(zhǎng)向160m，短向33.5m，最大懸挑26.2m，采用拉索-管桁架組合結(jié)構(gòu)，整個(gè)結(jié)構(gòu)主要由縱向17榀懸挑桁架及橫向前端的橫桁架和后端的環(huán)桁架組成，并通過(guò)鋼管混凝土柱支承在看臺(tái)結(jié)構(gòu)的混凝土柱上。在每根伸出屋面的鋼管柱頂斜拉三根拉索，并通過(guò)后索錨固在看臺(tái)的梁端部。針對(duì)結(jié)構(gòu)為扁殼膜結(jié)構(gòu)并地處錢塘江邊的特點(diǎn)進(jìn)行風(fēng)洞試驗(yàn)，并據(jù)此施加風(fēng)荷載；利用MSTcad及ANSYS軟件聯(lián)合進(jìn)行綜合工況靜力分析，得出的結(jié)構(gòu)位移、應(yīng)力等均滿足要求；利用MIDAS軟件進(jìn)行結(jié)構(gòu)整體穩(wěn)定性分析，滿足規(guī)范要求。對(duì)鋼管混凝土柱、支座球節(jié)點(diǎn)、管桁相貫節(jié)點(diǎn)等進(jìn)行驗(yàn)算；拉索張拉從中間向兩邊逐根對(duì)稱進(jìn)行，并對(duì)其進(jìn)行檢測(cè)。

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
