total load

By the analysis of the element loading situation and joint moment distribution of beam element after the moment of beam ends reaches its ultimate capacity M u, the necessity of modifying nodal overall load vector and the corresponding element stiffness matrix is pointed out.

根据对钢筋混凝土框架结构非线性全过程分析中杆单元的杆端弯矩达到极限承载能力 Mu 后的单元受力情况和结点弯矩分配的分析 ,提出了在杆端弯矩达到 Mu 后 ,应对结点总荷载列阵及相应的杆端弯矩和单元刚度予以修正的思路。
