Compared with steel structure , preflex composite structure has the advantages of not only saving steel but also being able to strengthen rigidity of structure members and the whole structure . in addition it has better characteristics in fireproof and antirust . compared with reinforced concrete structure , it has a lighter structure weight , higher strength , higher bearing capacity and better ductility as well 與鋼結(jié)構(gòu)相比,它不但節(jié)省鋼材,而且能夠增強構(gòu)件及建筑物的剛度,防火和防銹性能好;與鋼筋混凝土結(jié)構(gòu)相比,它不但重量較輕,而且具有較高的強度、承載力和良好的延性,能充分發(fā)揮鋼和混凝土兩種不同材料的受拉受壓特性。

The optimal model of truss structure is established , in which the cross sectional areas of bar are taken as design variables , the structure weight is taken as objective function . in the process , the reliability of structural displacement and bar stress and the fundamental frequency are taken as constraint functions . from the engineering practice , all the reliability constraints , which are implicit generally with the design variables , are equalized and transferred to the conventional explicit constraints 本文將主要考慮桁架結(jié)構(gòu)的優(yōu)化問題,首先建立數(shù)學(xué)模型,即以桁架的橫截面積為設(shè)計變量、以重量最小為優(yōu)化目標(biāo),位移、應(yīng)力等可靠性及基頻為約束條件;最后,從工程實際出發(fā),對結(jié)構(gòu)系統(tǒng)的可靠性隱形約束進行等價顯化處理,使之轉(zhuǎn)化為常規(guī)的橫截面積優(yōu)化問題。
