[摘要]充分考慮建筑結(jié)構(gòu)的特點,基于我國現(xiàn)行建筑結(jié)構(gòu)規(guī)范相關(guān)條款提出了適合梁、柱的高效優(yōu)化設(shè)計準則,分別以柱軸壓比和梁配筋率為指標構(gòu)造迭代格式。通過動態(tài)編程技術(shù)在建筑結(jié)構(gòu)設(shè)計專用的SATWE軟件上得到實現(xiàn),對一個30層的結(jié)構(gòu)進行了優(yōu)化設(shè)計,結(jié)果表明該方法是有效的、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.
Keywords:tall building structure; frame structure; criteria method; optimization design; feasible region
