［摘要］濟(jì)寧文體中心體育場下部采用鋼筋混凝土框架結(jié)構(gòu)，屋面采用空間鋼管桁架結(jié)構(gòu)。屋面體系由徑向主桁架、環(huán)向桁架與支撐一起構(gòu)成。重點(diǎn)介紹了該結(jié)構(gòu)在分析和設(shè)計(jì)中的關(guān)鍵問題,結(jié)構(gòu)體系的布置及荷載取值。采用ANSYS軟件進(jìn)行了考慮幾何及材料非線性的整體穩(wěn)定性分析，同時(shí)對(duì)該結(jié)構(gòu)采用的關(guān)鍵節(jié)點(diǎn)形式進(jìn)行了分析，對(duì)此類結(jié)構(gòu)的特點(diǎn)進(jìn)行了探討。計(jì)算分析表明，結(jié)構(gòu)構(gòu)件的應(yīng)力比、變形及結(jié)構(gòu)整體穩(wěn)定性均能滿足設(shè)計(jì)要求，同時(shí)通過在設(shè)計(jì)中采用滑動(dòng)型節(jié)點(diǎn)有效降低了結(jié)構(gòu)的溫度效應(yīng)。

Structure design on steel roof of Jining Sports Stadium
Yu Hui(The Architectural Design and Research Institute of Tongji University（Group）Co., Ltd., Shanghai 200092，China)
Abstract:Reinforced concrete frame structure and spatial tube trusses are adopted in Jining Sports Stadium. Roof system are composed of radial truss, link truss and brace. The key issues of design and research about the structure, the layout of the structure system and design loads were introduced. And the stability of the steel structure considering the geometric nonlinearity and material nonlinearity was analyzed by ANSYS software. The key joints were investigated. Some characteristics were also discussed. The results show that the stress ratio, deformation of structure member and stability of overall structure can meet the design requirements. The temperature stress of the whole structure is reduced by-slide joints.
Keywords:sports stadium; spatial tube truss; stability analysis; joint analysis
