摘要
本文以结构造价为目标函数、以钢筋混凝土结构设计规范及高层建筑结构设计规程的要求为约束条件,建立了筒中筒结构的设计数学模型。把结构的有限元计算理论同优化技术相结合,对整个结构采用分部优化法,而对筒中筒结构的各构件采用了带随机搜索的改进复合形法,实现了筒中筒结构的优化设计,并编制了相应的电算程序。最后,给出了算例。
In this paper, the optimal mathematical model of reinforced concrete tube-in-tube structure has been formulated by adopting the minimization of struc-tural cost as the objective function and the reguirements on 《Concrete StructureDesign Code》 and 《Highrise Building Structure Design Code》as the constraintsfunctions. Combining the optimal techniques with the structural finite-elementmethod, the optimal design of reinforced concrete tube-in-tube structure hasbeen carried out by using the improved complex of random searching method andits program OPTI has been presented. Finally, a numerical example is given in the paper.
