此程序用fortran编写 功能: 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 此程序出自《杆系结构程序设计》，有改动，原程序有错误-the procedure used to prepare fortran functions : 1. calculation of the load under the plane truss rod displacement and the axial force. Symbol axial force, the tension is positive, negative pressure. It also supports anti-hum calculating power. 2, the number of nodes truss, the first series to take movable joints, and then re-allocation fixed nodes. 3, the calculation of multi-state issues this procedure from the "bar structural design process," with changes, the original procedure is wrong
