| Abstract;This report contains results about experimental and analytical research work focused on the seismic safety of base isolated house. In case of a great earthquake bigger than design spectrum, the base isolated house may make shock acceleration (or collapse of upper structure in the worst case) by hard bumping on surrounding structures caused from an excess displacement response. To mitigate such undesirable behaviors we put overrun restraint stoppers around the isolation layer. Finally it is shown that inappropriate amount of stopper work negatively and the maximum response can be predictive on some level via equivalent linearization method using load-displacement relationship of isolation layer considering characteristics of stopper device.
