摘要
为提高钢筋混凝土框架结构优化效率,将离散化的萤火虫算法应用于钢筋混凝土框架结构优化中。建立离散萤火虫算法的数学模型,通过萤火虫的变量离散化和萤火虫的位置更新离散化将萤火虫改造为离散变量萤火虫算法,将其用于钢筋混凝土框架结构优化。钢筋混凝土框架结构优化算例结果表明:离散萤火虫算法的优化结果均能满足约束条件,其优化结果相比于遗传算法、改进遗传算法更优,效率更高,说明了该算法在钢筋混凝土框架结构中的适用性。
In order to improve the efficiency of reinforced concrete frame structure optimization,the dis-crete firefly algorithm is applied to the optimization of reinforced concrete frame structure.In this report,the mathematical model of the discrete firefly algorithm is established,and the firefly is transformed into the discrete variable firefly algorithm by discretizing the variables of the firefly and the position update discretization of the firefly,which is used in the optimization of reinforced concrete frame structure.The results of the optimization of reinforced concrete frame structure show that all the optimization results of the discrete firefly algorithm can satisfy the constraints,and its optimization results are better and more efficient than those of the genetic algorithm and the improved genetic algorithm,which illustrate the applicability of the algorithm in the reinforced concrete frame structure.
