The purpose of this research is proposing the optimal arrangement method of base-isolated devices in mid-story isolation structure by a genetic algorithm. First of all, the mid-story isolation structure is assumed to be a multi mass model. Next, the response value is calculated. And, the evaluation item is used and evaluated. The items to be evaluated in the genetic algorithm are' A) an eccentricity ratio, B) a vertical load on each isolator, C) a natural period, D) a yield force coefficient, E) a maximum response displacement, F) a story drift. We set up three evaluation methods. They are : (1). A-B-C-D, (2). A-B-D-E, (3). A-B-F. And using a result of analysis, we perform the time history response analysis. As a result, the response value was suppressed in case of (3).
