本程序主要用于计算空间刚架的位移。通过直接输入结构基本信息，如材料特征、截面形状、杆件信息、支座信息、杆件结点坐标、受荷状况等，经程序主体的运行后，显示出位移。-the procedure used mainly for the space frame displacement. Through direct input structure for basic information, such as material characteristics, geometry, information bar, bearing information, bar node coordinates, under such a situation, the main operating procedures, to show displacement.
