摘　　要：基于已有的带加强层框筒结构简化模型及某一超高层实际案例,运用单目标遗传算法,以结构顶点位移为优化目标函数,并结合若干约束性能指标,对框筒结构中加强层最优位置及设置数量进行优化设计研究,并应用MATLAB编制了基于单目标遗传算法的优化程序。研究结果表明:该优化设计过程具有较好的可行性与实用性;自动优化程序可以高效、便捷地给出带加强层框筒结构用于初步设计阶段的最优方案。An optimum design of the numbers and the locations of strengthened stories in the frame tube structure is studied based on an existing simplified model of frame tube structure with strengthened stories and a practical project. The top drift of the structure is considered as the optimal objective function and several performance indexes are utilized as constraint conditions.Meantime, an automatic optimization program is developed using a Single-objective Genetic Algorithm. Finally, some conclusions are drawn and the results indicate that the optimum design process possesses the characteristics of feasibility and practicability. The automatic optimization program can provide the optimal scheme for structures with strengthened stories during the preliminary design stage efficiently and conveniently.
