     this paper presents multi- objective genetic algorithm optimization response control of a 3d 9- storey building frame using mr dampers. equations of motion for the structure equipped with mr dampers have been established. three appropriate objective functions have been chosen to perform the and the number optimization process and location of mr dampers have been optimized. two different cases are studied as passive off and passive on in which the command currents of devices are set to minimum and maximum value, respectively. for each case, records from five ground motion data are applied to the building and ga is performed to determine the places where the dampers show their best performance. then, an optimal force control strategy is employed to gain the full capabilities of the mr dampers. results show that using the mr dampers in proper places can effectively reduce both the displacement and acceleration responses of the example building.
