چکیده:

This paper presents multi objective genetic algorithm optimization response control of a 3D 9-storey building frame using MR damper Equations of motion for thestructure equipped . quipped with MR dampers have been established Three approprate objective functions have been chosen to perform the optimization process and the number 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.
