本文先对组合桁架中节点板上升式连接件进行受力分析，并建立有限元分析模型。然后对其电算值与测试值进行比较，证明电算值与测试值吻合良好，应力分布规律及其破坏机理符合实际状况．
In this paper, the stress analysis of the riser joints in the gusset plate in the composite truss is firstly performed, and the finite element analysis model is established. Then the comparison between the calculated value and the measured value shows that the calculated value is in good agreement with the measured value, and the stress distribution law and failure mechanism are in line with the actual situation.
