（北京工業(yè)大學(xué)工程抗震與結(jié)構(gòu)診治北京市重點(diǎn)實(shí)驗(yàn)室，北京 100124）[摘要] 斜撐或人字支撐型阻尼減震方案中阻尼器的安裝位置和空間常常受限于工業(yè)工藝或建筑功能等方面要求，有時(shí)不能安裝在最優(yōu)位置處。隅撐式阻尼減震方案對(duì)空間的要求要稍小一些，但其變形幅度較小，需要布置較多數(shù)量的阻尼器。通過(guò)對(duì)單層單跨平面框架的理論分析和基于結(jié)構(gòu)控制benchmark模型的數(shù)值模擬，本文對(duì)隅撐式阻尼減震方案的有效阻尼比、結(jié)構(gòu)彈塑性地震響應(yīng)的減震效果等方面進(jìn)行了分析，結(jié)果表明：隅撐式阻尼減震方案在技術(shù)上是可行的，通過(guò)合理設(shè)計(jì)，可以獲得與斜撐式阻尼減震方案相近的減震效果；其工程造價(jià)要高于后者，但受到的建筑空間限制少于后者，可作為后者的備選方案。[關(guān)鍵詞] 隅撐式阻尼支撐；減震控制；benchmark模型中圖分類號(hào)：TU352.1 文獻(xiàn)標(biāo)識(shí)碼: A 文章編號(hào)：1002-848X(2013)S1-1189-06Studies on vibration reduction technology of knee-brace type dampingPeng Lingyun , Chen Huating , Xue Tao(Beijing Laboratory of Earthquake Engineering and Structural Retrofit, Beijing University of Technology, Beijing 100124, China)Abstract：Due to the requirements of industrial process or construction function, the space and installation of dampers in slant or herringbone bracing type are restricted, so as to not be installed in optimal locations. Damper installed like knee-brace needs smaller space, but its deformation is small and more quantity of dampers should be installed. The effective damping ratio and damping effect of seismic response in elastic-plastic structures are analyzed in this paper through theoretical analysis of the single layer and single span plane frame and on the base of numerical simulation of structure control benchmark model with knee-brace type dampers. The results show that: knee-brace type damping scheme is feasible in technology and damping effect, similar to slant bracings, can be obtained through reasonable design; on the other hand, the project cost is higher than the latter, but the limit of architectural space in it is less than the latter, so it can be used as the latter alternative.Key words: knee-brace type damping；seismic response control; benchmark model
