［摘要］鄭州市圖書館是鄭州市重點(diǎn)工程，因其建筑造型新穎、空間復(fù)雜，給結(jié)構(gòu)設(shè)計(jì)帶來(lái)了一定的難度。主體分為5個(gè)結(jié)構(gòu)單元，主樓兩個(gè)單元之間中部設(shè)有高大中庭，中庭頂部為玻璃采光頂，中庭兩側(cè)為大面積幕墻；主樓和裙房之間為消防通道，通道上部為玻璃采光頂。單元間連接體的設(shè)計(jì)是結(jié)構(gòu)設(shè)計(jì)的難點(diǎn)和重點(diǎn)。針對(duì)以往地震中連接體的震害特點(diǎn)，在連接節(jié)點(diǎn)的設(shè)計(jì)上，通過多道設(shè)防措施，以滿足頻遇及罕遇地震情況下的性能要求。另外，中部鋼斜筒、斜框架柱以及主入口長(zhǎng)懸臂雨篷等構(gòu)件的設(shè)計(jì)也是結(jié)構(gòu)設(shè)計(jì)的關(guān)鍵。［關(guān)鍵詞］結(jié)構(gòu)單元；連接體；索幕墻；鋼桁架；鋼斜筒；斜框架柱；弱連接

Abstract:Zhengzhou New Library, which is a very important construction project in Zhengzhou city, has a more difficult design process than others. The difficult factors come from its modern，fashion architectural figure and the complex space relation. The structure of the building includes five parts, and a huge atrium is designed between the two parts of the main building，which has a lighting roof at the top and curtain wall at its two facades. The fire passage has a lighting roof connecting with the main building and the skirt building. The connection between each part of building is the most important problem in the design process.Regarding the destroy model of the seismic action,the joint design is  base on multi-failure criteria in order to meet the performance requirement of frequent earthquake and rare earthquake.The design of steel slanting tube at the middle part of the atrium, slanting frame column, long cantilever steel beam of the rain cover at the main entrance and the others are also the key parts of the design.

Keywords:connection of structure；funicular curtain wall；steel truss；steel slanting tube；slanting frame column；weak connection
