Large amount of low-rise public accommodation buildings are remained in urban cities with difficulty for redevelopment, because of occupation by residents. Such residents are also tending to be aged and access improvements are also required. For solving those problem, additional isolation system on existing buildings are proposed. The system is composed of self-supporting additional floors on existing buildings, with energy-dissipation devices between existing buildings. In this paper, the structural characteristics and effects of this system are discussed, and easy estimation methods of their response are proposed.
