摘要
本文首先给出了开口薄壁杆系结构分析中非节点荷载的处理方法和步骤,然后推出了几种常见载荷作用下固端反力的计算式.文章最后通过算例说明:用实体杆的计算式来计算开口薄壁杆的固端反力会产生很大的误差。
This paper first puts forward the treating method and steps of non-node loads in structural analysis of thin-walled open cross sectionbars,then gives the formulas to calculate fixed-end forces which arecaused by some common loads.By means of an example,the paper finally states that using theformulas of common bar to calculate the fixed-end forces of thin-walledopen cross section bars would result in large errors.
