摘要
以框架-核心筒抗侧构件总造价为优化目标,使用VB语言编写了相应程序,调用LINGO作为优化工具进行数学摸型的优化求解,对框架-核心筒结构进行了优化研究。优化过程中通过虚功原理显式的表达了位移公式,将整体位移约束和强度约束放在同一层次进行优化以提高优化效率。通过算例验证了优化程序的合理性,研究结果对工程实际具有一定的参考价值。
This paper has taken the total cost of vertical structure as object function,and Visual Basic is used to write the program.The optimization model is solved by a mature software called LINGO.The program realizes the global optimization with both displacement constraints and strength constraints during the entire program,aiming to enhance the optimization efficiency.The displacement formula is derived explicitly based on the principle of virtual work.The reliability of optimization program is proved by an example,and the conclusion has practical value for engineering case.
