摘　　要：超高层混凝土框架-核心筒结构优化程序将主体结构造价作为目标函数,将位移约束和构件强度约束同时作为约束条件,并调用ETABS和LINGO进行整体优化。程序通过层间构件归并、结构对称性和标准层划分控制优化变量的数量。通过算例分析,程序基本实现超高层混凝土框架-核心筒结构优化的自动化,具有较好的工程应用价值。Super-High-Rise RC Frame-tube Structure Global Optimization Program takes total cost as the objective function and takes the displacement constraint and the strength constraint as the constraints.The program does the global optimization based on ETABS and LINGO.The number of optimization variables is controlled according to classification of structural components,structural symmetry and division of standard floors.Example analysis shows that the program has a good optimization effect on super-high-rise RC frame–tube structures,so it has practical value in engineering.
