摘要
为了探讨组合桁架中节点板上升式连接件内应力应变分布规律及其受力机理，本文先对整体测试的组合桁架中这类连接件进行受力分析，然后建立有限元模型，编制ＦＯＲＴＲＡＮ程序，计算出一系列应力，以便于后文中与实测值比较分析。
For exploring the stress and strain distrbution regularity and the applied force mechanism of gusset up connector in composite truss,the applied force of connector of this kind in the composite truss tested is analysed in this paper Then the finite element model is established,with the FORTRAN program worked out,and a series of stress are calculated The values calculated will be used to compare with the test ones,which will be reported in the next paper
