The objective of this paper is to analyze the effect of deformation control systems against pulse-like ground motions. In this paper, we carried out time history response analysis for the models of the equivalent SDOF system and the MDOF system equipped with hysteretic dampers, viscous dampers and stoppers. As a result, the following conclusions are obtained. 1) Against the maximal pulse-like ground motion, it sometimes happens that the additional hysteretic dampers increase the maximum story drift angle. 2) In all the cases, the additional viscous dampers decrease the maximum story drift angle. 3) Equipped with stoppers, there is a possibility to control unreasonable deformation against maximal pulse-like ground motions.
