［摘要］郑州市图书馆是郑州市重点工程，因其建筑造型新颖、空间复杂，给结构设计带来了一定的难度。主体分为5个结构单元，主楼两个单元之间中部设有高大中庭，中庭顶部为玻璃采光顶，中庭两侧为大面积幕墙；主楼和裙房之间为消防通道，通道上部为玻璃采光顶。单元间连接体的设计是结构设计的难点和重点。针对以往地震中连接体的震害特点，在连接节点的设计上，通过多道设防措施，以满足频遇及罕遇地震情况下的性能要求。另外，中部钢斜筒、斜框架柱以及主入口长悬臂雨篷等构件的设计也是结构设计的关键。［关键词］结构单元；连接体；索幕墙；钢桁架；钢斜筒；斜框架柱；弱连接

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
