［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、柱的高效优化设计准则，分别以柱轴压比和梁配筋率为指标构造迭代格式。通过动态编程技术在建筑结构设计专用的SATWE软件上得到实现，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。

Abstract:Considering the features of building structures, an efficient optimal criteria algorithm is presented for beams and columns of reinforced concrete buildings based on the regulations in the current design codes, and  the recursive formulation with respect to the steel ratio and axis compression ratio is proposed. The optimal criteria algorithm is realized in the popular structural design software SATWE using dynamic programming technique. The optimal design of a practical 30-story building illustrates the efficiency and feasibility of the proposed method.
