摘　　要：将K型偏心支撑应用到电除尘器钢支架中,用MIDAS软件建立中心支撑和K型偏心支撑的电除尘器钢支架动力分析模型,并进行动力非线性分析.结果表明,K型偏心支撑的设置可使电除尘器钢支架的层间剪力大幅度降低、层间位移和层间位移角增大,但满足规范要求,能够起到很好的耗能减震作用,满足"大震不倒"的抗震要求.The concentrically braced model and eccentrically braced models of k-type are simulated by MIDAS, and the dynamic non linear analysis is carried out subsequently. It turned out that the shear of the steel bracket is greatly reduced after the using of k-type support. The drift and interlayer displacement angle increased obviously. All of the results meet the requirements of the code. The steel frame of the new electrostatic precipitator consumes energy and absorbs the shock effectively and achieves the seismic fortification target in the strong earthquake.
