STSAD is used for checking calculation and design of steel structures composed of spatial members. The core part of the calculation is based on the spatial bar element, and the calculable structures include grid, shell and space truss. This program uses interactive man-machine interface, all operations are completed in the form of interface interaction.
STSAD用于由空间杆系组成的钢结构的验算和设计。其核心计算部分以空间杆元为基础，可计算的结构包括网架、网壳、空间桁架等。本程序采用交互式人机界面，所有操作均以界面交互的形式完成。 钢桁架程序（Ver 0.7 2006.6.11）修改说明 1. 增加自动优化半带宽的功能 2. 增加三维显示结构模型的功能（包括显示一部分结构） 3. 计算窗体与实际运算程序真正的同步 4. 修改荷载显示窗体的bug 钢桁架程序（Ver 0.6 2005.10.2）修改说明 1. 增加窗口放大的虚线 2. 修改全屏显示几何模型的bug 3. 修改“旋转”、“平移”、“窗口”不能及时释放的bug 4. 增加查询几何模型，节点信息的功能 5. 修改控制板上的名称 6. 令打开的缺省目录为work 7. 令窗口放大对几何模型有效 8. 禁止几何模型状态下“属性”、“荷载”的快捷键 9. 几何模型状态下，右键取消操作不再弹出菜单 10. 修改能打开dxf而不能打开DXF的bug
