摘要
多层建筑结构中设置摩擦消能支撑是以“柔性消能”减小地震反应、实现结构被动控制的有效途径之一。本文通过分析和计算Ⅰ０型、Ⅱb 型两种摩擦消能支撑装置在各种变形状态下的单元刚度矩阵［ＫＮＬ（ｔ）］，为摩擦消能减震结构体系在地震作用下的非线性时程分析提供了消能支撑单元的精确理论模型。
Frictional Energy Dissipation Brace(FEDB) has been proved to be an effective way for high-rise buildings to decrease seismic response by means of 'flexible energy dissipation' and to realize passive control. Through analyzing and calculating the element stiffness matrix [KNL(t)] of two types of FEDB: Ⅰ, and Ⅱ, in all deformation states,this paper provides an accurate theoretical model of FEDB element for the non-linear time-history analysis of energy dissipation system under a violent earthquake.
