【摘要】 为验证组合桁架中节点板上升式连接件有限元模型的准确性，寻求其应力分布规律，提供实际设计依据，本文对节点板上升式连接件的应力进行电算值与测试值比较，证明电算值与测试值吻合良好，并分析其应力分布规律及其破坏机理更多还原

【Abstract】 In order to prove the accuracy of the finite element model of the gusset up connector in composite truss,to seek its stress distribution regularity and to provide the basis for practical design,the calcuation values were compared with the measured ones of the gusset up connector in this paper The results showed that they corresponded with each other well Inaddition,the stress distribution regularity and destruction mechanism of the guesset up conector were analyzed更多还原
