[摘要] 剪切板耗能裝置是一種新型有效的耗能減震裝置，本文旨在研究高層結(jié)構(gòu)體系中耗能剪切板的減震效果。先介紹了低屈服點(diǎn)鋼剪切板耗能裝置的減振機(jī)理、動(dòng)力特性及恢復(fù)力模型，建立了安裝了剪切板耗能裝置的高層鋼結(jié)構(gòu)建筑的計(jì)算模型。結(jié)合具體工程實(shí)例，進(jìn)行多種剪切板耗能裝置的布置方案設(shè)計(jì)。加入耗能剪切板后，利用剪切板耗能，讓主體結(jié)構(gòu)在罕遇地震作用下保持彈性狀態(tài)。選取合適的地震波采用有限元法對每種布置方案進(jìn)行減震效果的分析。對整體位移、層間位移、動(dòng)力反應(yīng)加速度、反應(yīng)速度進(jìn)行分析比較，在經(jīng)濟(jì)上、技術(shù)上建立剪切板耗能裝置在上述結(jié)構(gòu)體系中的的最優(yōu)配置方案。

Abstract: Shear plate dissipating energy device is a land of modern efficient passive control device for suppressing vibration and dissipating energy This paper introduces the principle of low yield strength steel shear plate dissipating energy. A model capable of simulating the movements of high-rise steel building installed with shear plate dissipating energy devices is set up. The effects of suppressing vibration for different location of dampers are calculated by means of finite element analysis and compared. And combined with theoretical analyses, econonuc factors and technical factors, a
method about choosing the optimum devices position of energy dissipation devices is put forward  Finally, a practical example is given to illustrate the application of the method.
