This paper discusses the differences between the dynamic characteristics of frame strucutures having viscous or elastp-plastic damping devices, with and/or without amplifier mechanisms. The performances of them are compared by making use of the results computed by analyzing eigenvalue probrems of equivalent linearized strucutures and earthquake response simulation. Analytical models are the 10 story frame structures with dampers connected by 1) bracing system, 2) toggle system and 3) machanical wall system. The mechanical system is named as "Kamekabe", which consists of four links and wall in order to amplify story deformation. The results show that the toggle and Kamekabe systems have very higher energy absorption capacities comparing with that of the bracing system.
