【摘要】：主要針對(duì)自立式高聳鋼結(jié)構(gòu)振動(dòng)控制的優(yōu)化設(shè)計(jì)開展研究,根據(jù)自立式高聳鋼結(jié)構(gòu)的特點(diǎn),設(shè)計(jì)了環(huán)形調(diào)諧液柱阻尼器(Tuned Liquid Column Damper,TLCD),描述了其力學(xué)模型,并進(jìn)一步推導(dǎo)了高聳結(jié)構(gòu)環(huán)形TLCD控制的動(dòng)力學(xué)方程。采用Sigmoid函數(shù)和線性疊加法構(gòu)建了用于自立式高聳鋼結(jié)構(gòu)風(fēng)振控制的復(fù)合滿意度函數(shù),從而基于滿意度原理,并結(jié)合模式搜索算法,建立了自立式高聳鋼結(jié)構(gòu)多目標(biāo)優(yōu)化設(shè)計(jì)方法。針對(duì)某自立式高聳鋼結(jié)構(gòu)的風(fēng)振控制設(shè)計(jì),以環(huán)形TLCD的幾何參數(shù)為設(shè)計(jì)變量,以由頂點(diǎn)位移、質(zhì)量比和迎風(fēng)面積比組成的復(fù)合滿意度為目標(biāo),編制程序開展了所建立方法的數(shù)值算例研究。研究表明,該方法能夠快速有效地得到一組滿足工程需要的設(shè)計(jì)參數(shù),同時(shí)最優(yōu)參數(shù)和相應(yīng)設(shè)計(jì)目標(biāo)對(duì)權(quán)重組合的變異系數(shù)小于0.1,因此該方法具有較高的魯棒性,降低了多目標(biāo)優(yōu)化設(shè)計(jì)時(shí)權(quán)重系數(shù)選取的難度。
[Abstract]:In this paper, the optimal design of vibration control for self-supporting high-rise steel structures is studied. According to the characteristics of self-supporting high-rise steel structures, a tuned liquid column damper (tuned Liquid Column damper) is designed, and its mechanical model is described. Furthermore, the dynamic equations of annular TLCD control of towering structures are derived. By using Sigmoid function and linear superposition method, the composite satisfaction function for wind vibration control of self-supporting tall steel structures is constructed, which is based on the satisfaction principle and combined with the pattern search algorithm. A multi-objective optimization design method for self-supporting high-rise steel structures is established. For the wind-induced vibration control design of a self-supporting high-rise steel structure, the geometric parameters of annular TLCD are taken as design variables, and the composite satisfaction degree composed of vertex displacement, mass ratio and upwind area ratio is taken as the goal. A numerical example of the established method is developed. The research shows that this method can get a set of design parameters to meet the engineering needs quickly and effectively, and the coefficient of variation of the optimal parameters and the corresponding design objectives to the weight combination is less than 0.1, so the method has high robustness. The difficulty of selecting weight coefficient in multi-objective optimization design is reduced.
