（中國建筑設(shè)計(jì)研究院，北京100044）[摘要]佛山高明體育館大跨度鋼結(jié)構(gòu)與混凝土結(jié)構(gòu)完全脫開，正立面由7個(gè)并列的拱形門式鋼架組成，相鄰拱形斜柱相交形成并列M形結(jié)構(gòu)。大跨度鋼結(jié)構(gòu)屋蓋由并列圓柱殼組成，在相鄰圓柱殼相交的部分設(shè)置三角形空間桁架。并在側(cè)立面斜柱間設(shè)置預(yù)應(yīng)力拉桿支撐。該工程結(jié)構(gòu)形式新穎，受力合理，經(jīng)濟(jì)性較好。本文介紹了高明體育館結(jié)構(gòu)體系的布置特點(diǎn)、荷載取值、穩(wěn)定性分析及焊接節(jié)點(diǎn)的設(shè)計(jì)等，可為類似工程提供參考。[關(guān)鍵詞]體育館;大跨度結(jié)構(gòu);圓柱殼;三角桁架中圖分類號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S1-0281-05Design on large span steel structure of Foshan Gaoming GymnasiumLi Li, Fan Zhong, Zhang Yu, Cao He, Liu Xinying(China Architecture Design & Research Group, Beijing 100044, China)Abstract: The large span steel structure of Foshan Gaoming Gymnasium which is separated with concrete structure is composed of seven parallel arched portal frames. Adjacent arched columns intersect with each other and form an M-shaped structure. Also, the roof is consisting of seven cylindrical shells, with triangular truss installed between every two adjacent shells. In side elevation, prestressed tension rods are used between the inclined columns. In this project, architectural effects and structural performance are consistent with each other and bring forth integrated harmony. This article describes the arrangement of the structural system, load value, stability analysis as well as design process for welded joints, which provides a reference for other similar projects.Keywords: gymnasium; cylindrical shells; triangle truss; welded joints
