摘　　要：台州国际博览中心项目大跨度空间连廊与两侧主体结构通过双向滑动式球形铰支座连接,下方支撑6组树杈式圆管钢柱,其中双曲屋面桁架是钢结构深化设计的重难点。通过模型建立、节点优化、分段方式确定、滑移节点设计、屋面碰撞分析等方面,详细阐述了台州国际博览中心项目的深化设计。通过钢结构深化设计技术的深入推行,以及菱形双曲桁架节点优化的研究,可为同类建筑钢结构工程的设计、施工提供参考。The large-span spatial corridor of the Taizhou International Expo Center project is connected to the main structures on both sides through bidirectional sliding spherical hinge supports,with six sets of branched circular steel columns supported below.The hyperbolic roof truss is a key and difficult point in the deepening design of the steel structure.The detailed design of the Taizhou International Expo Center project was elaborated through model establishment,node optimization,segmentation method determination,sliding node design,roof collision analysis,and other aspects.The in-depth implementation of steel structure deepening design technology and the research on optimization of diamond hyperbolic truss nodes can provide reference for the design and construction of similar building steel structure projects.
