This paper investigated the response of building that has a nonlinear isolated device at the bottom floor. The isolated structure resonates with long period earthquake and response displacement increases. In order to reduce the vibration of the building, multiple Tuned Mass Damper are installed at the highest floor. In this study, the multiple tuned mass damper (MTMD) parameters are considered. The MTMD’s optimal parameters that minimize response displacement of the structure’ top layer is found. Genetic Algorithm (GA) method is used for optimizing MTMD’s parameters. The building is vibrated under some case of earthquakes. .The results show the good effectiveness of GA method.
