摘要:

采用鹰策略优化算法处理钢筋混凝土肋梁楼盖优化问题, 包括普通楼板和地下车库顶板的优化. 对于不同的柱网情况, 在满足相应约束条件的情况下, 以造价为目标函数, 得出最优的梁平面布置方式、梁板的最优截面尺寸及对应配筋. 结合国家规范, 对一个 8 m$\times $6 m 柱网的车库顶板及普通楼板的梁板结构布置分别进行整体优化, 优化效果良好, 可应用于实际 工程.

Abstract:

The eagle strategy is used to optimise a reinforced concrete (RC) ribbed floor system, including floors and underground garage roofs. This study takes the cost as an objective function and satisfies the constrained condition such that an optimal layout is obtained for different column grids. In addition, an optimal section of the beam and slab as well as the corresponding reinforcement are obtained. The RC ribbed floor is optimised according to the Chinese standard, whose two column grids are 8 and 6 m, respectively. The effect of optimisation is determined to be sufficient and applicable to practical engineering.

Key words: eagle strategy, discrete variable, ribbed floor, optimisation design
