| 摘 要： | 中国国家博物馆钢桁架结构跨度大、荷载大,使得钢桁架与混凝土结构连接处的反力巨大。为了使钢和混凝土协调工作,连接部件的合理设计是一个关键问题。本项目中,钢桁架与混凝土结构主要有两种位置关系,一种是钢桁架与混凝土结构侧面连接;另一种是钢桁架与混凝土结构顶面连接。对这两种连接方式分别进行了方案的对比和介绍。对于侧面连接区域,采用了暗桁架的连接方式,并将暗桁架杆件形式从实腹式截面调整为两块钢板,在保证了有效传力的同时,满足了钢筋布置的要求。同时还进行了有限元分析,对节点设计方法给予了验证。对于顶面连接方式,采用与施工方案相结合的节点设计方式,通过滑动支座释放部分水平反力。通过分析计算确立了合理的连接构造。

| Abstract: | The steel truss of National Museum of China is a large-span and high-loaded structure system,which produces high reaction force on the connection between steel truss and concrete structure,thus the design of reasonable connection is a crucial issue for the coordination between steel and concrete.There are mainly two connection types between steel truss and the concrete structure in this project: the steel truss is connected on the side face of the concrete structure,and the steel truss is located on the top... |
