摘要
结合ANSYS参数化编程,基于MATLAB软件编制相应的优化程序,以一座多跨矮塔斜拉桥为例,选择主梁弯曲应变能最小为优化目标,将遗传算法的基本原理应用于桥梁结构的索力优化计算中,优化结果表明结构受力得到了有效改善。
A program is developed based on MATLAB software and ANSYS software. A multi-span extradosed bridge is cited as an example and was analyzed. With objective function the minimum strain energy of main beam, the genetic algorithm is applied to the optimization of cable forces of bridges, optimized structure has improved mechanical condition.
