[摘要]一般情況下,最大層間位移角在結(jié)構(gòu)方案調(diào)整下的演變模式與典型特性主要取決于其平動分量。兩者的強(qiáng)相關(guān)性決定了優(yōu)化最大層間位移角應(yīng)從研究平動成分的優(yōu)化策略入手。建立了最大層間平動位移角與結(jié)構(gòu)布置方案的聯(lián)系數(shù)學(xué)模型,并量化分析了兩者的敏感性關(guān)聯(lián)。研究結(jié)果表明:水平側(cè)向荷載作用下,依據(jù)結(jié)構(gòu)的側(cè)移變形形態(tài),合理選擇最大層間平動位移角的配套優(yōu)化調(diào)整方案,能輔助結(jié)構(gòu)工程師進(jìn)行高效決策;地震作用下,應(yīng)優(yōu)先采用保證結(jié)構(gòu)剛度降幅低于自重降幅的優(yōu)化調(diào)整方案,以合理優(yōu)化結(jié)構(gòu)造價。

Abstract: Generally speaking,the evolution mode and typical characteristics of the maximum inter-story displacement angle under the adjustment of structural schemes are primarily determined by its translational component. The strong correlation between them determines that the optimization of the maximum inter-story displacement angle should start with optimizing the translational component. A mathematical model about the relationship between maximum inter-story translational displacement angle and structural configuration was build, and quantitatively analysis the sensitiveness of this relationship. The results of this research shows that under the action of horizontal lateral load, matching appropriate optimization adjustment scheme of the maximum inter-story translational displacement angle according to the lateral deformation form of the structure, can assist the structural engineer to make decision efficiently; under the action of earthquake, the optimization adjustment schemes which ensure the structural stiffness reduction is lower than the self-weight reduction should take precedence, is able to reasonably reduce the cost of construction.
Keywords:high-rise shear wall structure; structural optimization; maximum inter-story displacement angle; lateral displacement; translational component
