摘　　要：通过对两种节点形式下的全T型钢桁架承载力的试验研究,分析桁架承载力的理论计算依据,并借助有限元分析软件对桁架节点进行应力分析。对试验值与有限元计算值进行对比,验证有限元软件分析全T型钢节点的适用条件,分析节点的受力性能的特征及优越性,为推广T型钢在桁架中的应用提供依据。The theory calculation foundation of truss capacity is analyzed through the test of bearing capacity of full T-section truss with two types of joints.Besides,the experiment result is compared with finite element analysis result of truss joint,so that it can be testified the applying condition of finite element analysis on cut T-section truss joint,it is analyzed the features of the forced performance and advantage of the joint,which provides a support for extensive application of T-section steel in trusses.
