[摘要] 研究通過(guò)優(yōu)化平臺(tái)HyperStudy調(diào)用結(jié)構(gòu)分析軟件SAP2000進(jìn)行結(jié)構(gòu)抗震優(yōu)化設(shè)計(jì)。利用SAP2000的API功能開(kāi)發(fā)了OptiDesign程序，OptiDesign可以調(diào)用SAP2000進(jìn)行求解并將SAP2000的計(jì)算文本結(jié)果輸出及反饋到HyperStudy，從而實(shí)現(xiàn)了優(yōu)化流程的自動(dòng)控制，提高了結(jié)構(gòu)優(yōu)化效率。以結(jié)構(gòu)樓層位移角、位移比和豎向構(gòu)件軸壓比等作為優(yōu)化約束條件，以構(gòu)件截面尺寸為優(yōu)化變量，以結(jié)構(gòu)總重量最小為目標(biāo)對(duì)某框架結(jié)構(gòu)進(jìn)行優(yōu)化。算例結(jié)果表明，本文方法可作為建筑結(jié)構(gòu)優(yōu)化的一種新手段。

Abstract: Seismic structural design optimization was performed by HyperStudy calling structure analysis software SAP2000. The program OptiDesign was developed base on the function of SAP2000 API, it can call SAP2000 solving and feedback text results of SAP2000 to HyperStudy. The optimal process was controlled automatically and the efficiency of structural optinuzation was improved. The total mass of a frame structure was optimized under the optimal constraints of drifts, displacement ratio, axial compression ratio and optimal variables of member section size. The optimal example shows that this method can be used as a new means in building structural optimization.

Keywords: building structure; structural seisnuc design optimization; HyperStudy
