摘　　要：传统的低效率粗放型建筑施工逐渐向工业化和产业化调整,然而却忽略了建筑的经济效益。为了提高建筑工程的经济效益和施工质量,研究以截面尺寸为主要指标对钢筋梁柱结构进行优化,通过参数化分析,建立了梁柱节点的约束函数,最后运用天牛须遗传算法进行优化。结果表明,梁、柱单元承载力都符合规范要求,其受力性能能够得到保障。与基准算法相比,天牛须算法的初始迭代速度和后期的稳定性都得到了显著的提高,节省了总成本的8.96%和11.87%。天牛须遗传算法可以使整个结构的成本更低,同时也可以充分利用混合算法的全局优化和局部优化的功能。研究所提结构优化方案可以降低建筑成本,降低能耗。The traditional inefficient extensive building construction gradually adjusts to industrialization and industrialization,but ignores the economic benefits of the building.In order to improve the economic benefits and construction quality of the construction project,the paper optimizes the steel beam and column structure with the section size as the main index.Through the parametric analysis,the constraint function of the beam and column node is established.The bearing capacity of beam and column elements meet the requirements of the code,and its mechanical performance can be guaranteed.Compared with the benchmark algorithm,the initial iteration speed and later stability of the antennae are significantly improved,saving 8.96%and 11.87%of the total cost.The genetic algorithm can reduce the cost of the whole structure and make full use of the function of global optimization and local optimization of the hybrid algorithm.The structural optimization scheme proposed in this study can reduce construction costs and reduce energy consumption.
