简化力法计算的两种补充方法

Two Supplement Methods for Simplifying the Calculation of Force Method

用力法计算超静定结构时 ,需要求解由多余未知力组成的联立方程。结构的超静定次数增加时 ,多余未知力随之增加 ,解算方程的工作量便迅速增加。为减少工作量 ,提出了两种简化算法。

Combined equations have to be solved in the analysis of a super static determined structure with force method. The equations take the unknown forces as the variables to be solved. The calculation scale increases rapidly as the number of the abundant unknown forces( super static determined order) increases. To this end, two simplifying methods are proposed. They could be applied to the calculation of the optimal designing of structures.
