［摘要］ 介紹了鎮(zhèn)江體育會展館屋蓋結(jié)構(gòu)體系的方案比選，屋面體系的布置，節(jié)點連接形式及支座形式的選擇；建立了屋蓋結(jié)構(gòu)、圍護鋼桁架結(jié)構(gòu)和下部鋼筋混凝土框架結(jié)構(gòu)的分離模型和整體模型，并對兩種模型中各結(jié)構(gòu)在豎向作用和水平作用下的內(nèi)力與變形特性進行了分析比較，結(jié)果表明在豎向作用下兩種模型受力特性相差不大，在水平作用下則存在差別。根據(jù)預(yù)應(yīng)力設(shè)計原則，確定了拉索截面和張拉控制力；同時介紹了屋蓋結(jié)構(gòu)中關(guān)鍵節(jié)點的設(shè)計。

Abstract:The structural system，roof system and support style of roof of the exhibition gymnasium of Zhenjiang were introduced. Separated model and integrated model of the roof structure，the enclosure structure and the reinforced concrete frame structure were developed. The internal force and deformation of each structure under horizontal and vertical load in two kinds of models were compared. The results indicate that the internal force and deformation in two kinds of models are similar under vertical actions，while different under horizontal actions. According to the principles of prestressing, the sections and tension control stress of prestressed cables were determined. Design of key joints in the roof structure was also introduced.
Keywords:exhibition gymnasium of Zhenjiang; roof structure; truss string structure; prestress; joint design
