摘　　要：钢管桁架结构中采用圆支管端部压扁与主管连接的节点,具有制造简单、安装方便的特点,非常适用于小型或临时建筑结构。本文综述了楔形压扁、全压扁和部分压扁等几种常用的支管端部压扁的形式、特点和其制作工艺,介绍了目前国外对支管端部压扁的N型、K型、T型和X型节点强度的研究工作和相关的计算方法,可供结构工程师设计时参考,以期促进支管端部压扁节点的钢管桁架结构在我国的应用。The joint between a circular hollow section brace with flattened end and a chord in tubular truss structures is quite suitable for a structure with small size or for temporary use due to its simple fabrication and convenient connection. Several types of braces with flattened ends commonly applied, such as cropped end, fully flattened end and partially flattened end,and their features and manufacturing processes are summarized in the paper. Recent research in the world on strength of N, K, T and X-joints with the braces flattened at ends as well as relevant calculation methods are presented, which can be used by structural engineers for design and promotes the application of tubular truss structures with the kinds of joints in China.
