［提要］基于位移準(zhǔn)則優(yōu)化算法，針對(duì)高層建筑鋼結(jié)構(gòu)特點(diǎn)，給出了基于通用表達(dá)的風(fēng)荷載下高層建筑鋼結(jié)構(gòu)位移準(zhǔn)則優(yōu)化算法公式，提出了層間位移限制的整體約束，和強(qiáng)度、穩(wěn)定與撓度限制的局部約束相結(jié)合的實(shí)用綜合優(yōu)化算法策略。算例分析表明，此綜合優(yōu)化算法對(duì)鋼框架與鋼框撐結(jié)構(gòu)均具有較好的收斂性，且優(yōu)化結(jié)果同時(shí)滿足了整體與局部約束，具有很好的直接實(shí)用性。

［關(guān)鍵詞］高層鋼結(jié)構(gòu)；結(jié)構(gòu)優(yōu)化；位移準(zhǔn)則法

Multilever Optimization Research for Structural Design of Tall Steel Buildings/Gong Hai, Li Guoqiang, Zhang Zhiyong (College of Civil Engineering, Tongji University, Shanghai 200092, China)

Abstract:Based on the existed fruits in the displacement rule design and aiming at optimization of tall steel buildings, the optimization calculation method based on the displacement principle of high-rise steel structure under wind load with common expression is presented. The applied integrated optimization method with the combination of integral and local restriction is put forward. The results of case analysis show that the new method has good optimization convergence and practicality.

Keywords:tall steel building; structure optimization; displacement rule design
