考虑节点域剪切变形的空间钢框架结构分析
|
摘要
根据节点域的变形特点，提出了一种考虑节点域剪切变形影响的空间钢框架结构的分析方法。并应用该方法对纯框架、支撑－框架体系进行了分析比较。算例表明，该方法简单易行．便于程序实现，计算结果可靠。
An analytical method for a spatial steel frame strocture with the effects of the shear deformation of the joint panels taken into account is proposed according to the deformation features of the nodal zones.The anaysis and comparison of a pure frame and braced frame systems arc also conducted using this method.It is indicated by some calculation examples that this method is simple and practicable,and convenient for realizing the procedures with reliable calculated results.
