摘要
结构优化分析中,必须不断修改并解算大型线性方程组。当只对少量主要结构单元的参数进行调整时,本文解法可迅速得出新的结构分析结果,从而提高重分析的计算效率。
The analysis of structural optimazation is subject to a constant modi- fication and calculation of a set of large-scale linear equations.In case only the parameters of a few major structural elements are revised,the solution presented here will promptly yield the results of the renewed an- alysis,thus evidently enhancing its computational efficiency.
