摘要
基于矩阵位移法 ,提出结构杆件撤除后简化分析的一般方法 ,视杆件撤除后新结构的解为原结构的解与原结构上加以关联荷载解的叠加 ,利用原结构的解和刚度矩阵求解新结构 ,使计算工作量大大减少。导出求关联荷载的一般算式 。
Based on the matrix displacement method, a general method of simplied analysis is presented in this paper after the members of structure have been removed. Adding the solution of old structure to the solution of relative load which acts on old structure will give rise to the solution of new structure. By using the soultion of old structure and stiffness matrix to solve new structure, the volume of calculation will be greatly decreased. The general calculating formula for relative load is given. The formula in reference 〔1〕 is only a special case in this paper.
