摘要
充分考虑建筑结构的特点,基于我国现行建筑结构规范相关条款提出了适合梁、柱的高校优化设计准则,分别以柱轴压比和梁配筋率为指标构造迭代格式。并通过动态编程技术在大型有限元软件ANSYS上进行了程序实现,对一个30层的结构进行了优化设计,结果表明,该方法是有效的可行的。
Considering the features of building structures,this paper presents an efficient optimal criteria algorithm for beams and columns of reinforced concrete building based on the regulations in the current design codes,and proposes the iterative formulation with respect to the steel ratio and axis compression ratio.The optimal criteria algorithm is realized in the large finite-element software ANSYS using dynamic programming technique.The optimal design of a practical 30-story building illustrates the efficiency and feasibility of the proposed method.
