平面钢桁架的结构计算与程序设计

Structure Calculation and Program Design for the Plane Steel Truss

从实际设计出发，以现行国家规范为依据，利用直接刚度阵法对平面钢桁架进行静力分析，并介绍了对杆件进行强度、稳定验算的方法，同时介绍了运用此方法编制直接用于钢结构设计的程序方法。

To begin with practical designing and according to the current national criterion, the static analysis of a plane steel truss is made by means of the direct rigidity array method. The paper introduces one method for calculation of the strength and stability existing in the purlins. At the same time, the description of this method is used to compile the programs to meet the design of the steel construction directly.
