[摘 要] 黏滯阻尼墻是一種主要應(yīng)用于建筑結(jié)構(gòu)的速度相關(guān)型消能器。本文設(shè)計了一種新型黏滯阻尼墻,并通過水平動力加載試驗,研究新型黏滯阻尼墻在不同振動頻率和位移幅值下的阻尼力與位移的關(guān)系,探討了新型黏滯阻尼墻的滯回特性,以及振動頻率、位移幅值、速度、循環(huán)特性等對新型黏滯阻尼墻動力性能的影響。研究表明,新型黏滯阻尼墻耗能效果較好,其阻尼力與速度有關(guān),而無頻率相關(guān)性;地震作用下,其耐久性較好。[關(guān)鍵詞] 結(jié)構(gòu)控制;消能減震;黏滯阻尼墻;動力性能中圖分類號:TU317+.1 文獻標識碼:A 文章編號:1002-848X(2013)S1-0593-06Experimental study on dynamic performance of a new viscous damping wallZhang Zhiqiang1,2,Xia Dongping1, Li Aiqun2,Liu Kang an3,Peng Fengbei3( 1 School of Civil Engineering,Southeast University,Nanjing 210096, China; 2 Southeast University,Key Laboratory of Concrete and Prestressed Concrete Structures of the Ministry of Education,Nanjing 210096, China; 3 Nanjing DAMPER Science and Technology Engineering Co.,Ltd.,Nanjing 211000, China)Abstract:Viscous damping wall is type of velocity related damper applied to building structure.A new type of viscous damping wall has been designed,and dynamic performance experiments on VDW under different frequencies and displacement have been performed.The relationship of dynamic performance to loading frequency ,displacement range,velocity and cyclic property are discussed in this paper.The experiment result show the VDW has nice energy dissipation ability,and it’s daming force relates to velocity,but not frequency.The durability of VDW is good under earthquake.Keywords: structure control; energy dissipation; viscous damping wall; dynamic performance作者簡介:夏冬平,碩士研究生,Email: xiadongping@gmail.com。
