[提要]  針對拉線鐵塔的結(jié)構(gòu)特點(diǎn)，建立了結(jié)構(gòu)優(yōu)化設(shè)計(jì)模型，把離散變量優(yōu)化方法與結(jié)構(gòu)有限元法相結(jié)合，完成拉線鐵塔優(yōu)化設(shè)計(jì)計(jì)算軟件的研制。應(yīng)用結(jié)果表明該軟件具有較好的適應(yīng)性和實(shí)用性，優(yōu)化效果明顯。
[關(guān)鍵詞]  拉線鐵塔優(yōu)化設(shè)計(jì)  離散變量

A structure optimal design model is established in accordance with special structure characteristics of cable stayed iron tower. Combining the method of searching discrete variables with the structure finite element method,a structure optimal design calculating software is developed. The software presents the characteristics of sound adaptability as well as applicability. The result of optimal design is effective.
Keywords:  cable stayed iron tower; optimum design; discrete variable
