［摘要］河北联合大学图书馆主楼为现浇钢筋混凝土框架-剪力墙结构体系，上部结构采用超大跨度桁架和大跨度型钢混凝土梁进行转换，介绍了图书馆主楼的结构设计特点及采取的相关措施。通过YJK和PMSAP两种软件进行计算，详细分析了转换桁架的形式、节点连接方式以及施工顺序对周边构件和整体结构的影响。结合施工深化设计优化了转换桁架的关键节点构造，并根据实际受力和施工情况将桁架设计成上下弦杆为型钢混凝土构件，中弦杆、斜撑和竖杆为纯钢构件的形式，对今后的转换结构设计提供一定的借鉴意义。［关键词］河北联合大学图书馆; 大跨度转换桁架; 结构设计; 施工模拟; 节点优化中图分类号：TU318+.2 文献标识码：A 文章编号：1002-848X(2016)03-0070-06
Structural design of main building of Hebei United University LibraryZhang Jinhai, Wang Xiang′an, Wang Heng, Shan Yukun, Wei Qiang, Liu Yanru, Meng Fanhui(Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China)Abstract:The reinforced concrete frame-shear wall structure system is adopted in main building of Hebei United University Library. The super-long span truss structure and long span steel reinforced concrete beam are used for the transformation of upper structure. The design characteristics and relevant measures of the main building were introduced. The transfer truss form, node connection method and the effect of construction sequence on surrounding components and the overall structure were analyzed by the programs of YJK and PMSAP. The key nodes of transfer truss were optimized though deepening the design. According to the actual force and construction condition, the transfer truss was designed of the combination that the up and down chord using steel reinforced concrete and the middle chord, diagonal brace, steel vertical column using pure steel, which provides reference for the design of transfer structure in the future.Keywords:Hebei United University Library; long span transfer truss; structural design; construction simulation; node optimization
