摘要
鉴于目前密肋壁板结构的优化设计研究仍处于构件阶段,在课题组前期研究的基础上,针对多层密肋壁板结构,进行了以造价最小为目标的优化设计方法研究:提出了结构的优化设计原理;建立了密肋复合墙体造价优化设计数学模型,并采用遗传算法对其进行计算,最后给出了计算算例.理论分析与计算结果表明:提出的多层密肋壁板结构优化设计方法合理、可行,优化效果显著,具有一定的工程实用意义.
In view of the fact that the study on the optimization design of multi-ribbed slab structure still rests on the member of the structure and based on previous study results, the optimization design method of the multi-storied multi-ribbed slab structure is studied in this paper. The principle of optimization design for the structure is put forward. Then the optimization design mathematical model of the multi-ribbed composite wall is established, and the Genetic Algorithm （GA） is employed to solve the proposed model. At the same time, a case of optimization design is given. Theoretical analysis and calculated results show that the optimization design method for the multi-storied multi-ribbed slab structure was found reasonable, practicable and having some meaning to the practical engineering.
