平面、空间桁架的计算程序：1、是计算在载荷作用下的平面桁架位移以及杆件的轴力。轴力符号规定，受拉为正，受压为负。另外还哼计算支座反力。 2、对桁架的节点编号，采取先编可动节点，接着再编固定节点。 3、计算多工况问题-Plane, the calculation of space truss: 1, is included in the load displacement of the plane truss, as well as the axial force rod. Symbol prov

桁架结构有限元分析的MATLAB程序，用于计算节点位移、杆轴力以及支座反力-MATLAB program for finite element analysis of truss structure，can be used for calculation of node displacment, bar axial force and support reaction force
