简述了利用离散变量优化设计方法，来解决土建领域内结构配筋的优化设计问题，使得设计结果不但是一种可用方案，而且是一种最优方案。并进而完成了对单层工业厂房排架柱的优化配筋设计，得出了令人满意的结果。 In this paper, the optimization design method of discrete variables is used to solve the problem of structural optimization of structural reinforcement in the field of civil engineering, making the design result not only a usable solution but also an optimal solution. It has also completed the design of optimized reinforcement for single-story industrial plant bay columns and achieved satisfactory results.
