摘　　要：钢桁架结构是工程应用非常广泛的一种结构体系。以实际工程的钢桁架结构为背景,该钢桁架结构主要受力构件采用箱形截面,对其关键节点进行设计、分析及优化,并在此基础上拓展到H型钢构件的"K+T"形节点设计,提出了"K+T"形节点设计中存在的问题和优化方案。Steel truss structure has been widely used in engineering application. Based on an actual engineering project of steel truss structure,the box-section structure members was mainly used as the chief bearing elements in the steel truss,and the key joints of the steel truss were designed,analyzed and optimized. On this basis,an improved design scheme for the K ＋ T joint of H-beam elements was proposed,as well as some common problems and optimization schemes.
