摘要
本文提出采用有限元法对U型钢可缩性支架进行计算。说明了支架搭接段的处理方法;讨论了支架缩动后其几何形状及残余内力的计算方法。
In this paper,the finite element method for U shape yieldable steel ribs is presented. It describles how to deal with the overlap sections of yieldable steel ribs in the calculation of internal forces in the support,using the finite element method.It analyses the variation of the shape of steel ribs and calculation of internal residual forces resulted from yielding of steel ribs.
