基于矩阵位移法，提出了用于分析杆件撤除对平面刚架结构影响的简化计算方法．与以往不同，本法仅将杆件撤除视为在原结构上增加荷载工况，因此。无需重建总体刚度矩阵即可用于分析杆件撤除对结构的影响．本方法的计算速度比矩阵位移法快很多，其例表明，两种方法的计算结果一致
Based on the matrix displacement method, a simplified calculation method for analyzing the effect of bar removal on the plane frame structure is proposed. Different from the past, this law only considers removal of bars as adding load conditions to the original structure. It can be used to analyze the effect of bar removal on the structure without reconstructing the overall stiffness matrix. The computational speed of this method is much faster than the matrix displacement method. The example shows that the calculation results of the two methods are consistent
