（北京奇太振控科技發(fā)展有限公司，北京100037）[摘要] 主要研究目的是探索一種高層，特別是超高層結(jié)構(gòu)抗風(fēng)的新體系——使用質(zhì)量相對(duì)較小的TMD與少量直接安置的阻尼器協(xié)同工作體系。將這種體系與傳統(tǒng)的抗風(fēng)TMD系統(tǒng)在抗風(fēng)方面進(jìn)行詳細(xì)分析。為某150m高層混凝土結(jié)構(gòu)及天津富力廣東大廈（420m）分別設(shè)計(jì)了對(duì)應(yīng)的兩種主要用于抗風(fēng)的減振方案，并將相同工況下各自的減振效果加以比較。使用風(fēng)時(shí)程函數(shù)進(jìn)行數(shù)值積分，計(jì)算結(jié)果表明，較小的TMD與少量阻尼器協(xié)同工作可以和單獨(dú)用大型的TMD起到同樣的抗風(fēng)效果，且在高效的套索連接形式的幫助下，前者的成本遠(yuǎn)低于后者。[關(guān)鍵詞] 阻尼器;TMD;抗風(fēng);套索;聯(lián)合使用中圖分類(lèi)號(hào)：TU352.1 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S2-0720-06作者簡(jiǎn)介：彭程，助理工程師，Email：orange_peng@foxmail.com。Discovery for a new system, using fluid viscous damper and tuned mass damper (TMD) together in high-rise structure for wind-induced vibration reductionPeng Cheng, Chen Yongqi(Beijing Qitai Shock Control and Scientific Development Co., Ltd., Beijing 100037,China)Abstract : It is the main point that to study a new system, using relatively lighter TMD as well as a small quantity of dampers work cooperatively for high-rise building, especially super high-rise building. This system as well as traditional TMD system were completely discussed. In this paper, the two approaches mainly for wind resistance are designed for a 150-meter-high concrete structure and Tianjin FULI Guangdong Tower (420m) respectively, and compared the damping effects of them under the same load case. Analyses in this paper are proceeded with numerical integration using wind time-history excitation. The results show that, small TMD and few dampers work cooperatively can perform same effect as with the huge TMD operates by itself, and thank for toggle-brace-dampers, the cost of the former is much smaller than the later.Keywords : damper; TMD; wind resistance; toggle; work cooperatively
