     in this paper, a fifteen-story reinforced concrete (rc) building with asymmetric plan equipped by semi-active tuned mass damper (stmd) is modelled to evaluate the seismic responses under the earthquake acceleration. modelling of the structure is done by considering members connected with a rigid floor diaphragm such that has three degrees-of-freedom at each floor, i.e., lateral displacements in two perpendicular directions and a rotation about the vertical axis of the third dimension. a matlab program has been developed to calculate the building structural mass, stiffness and damping matrices based on the number of stories, the plans’ geometry and loadings, each column’s location and specifications and the damping ratio of the structure. a fuzzy controller is employed to control the applied voltage of a semi-active magneto-rheological (mr) damper working parallel with the tuned mass damper attached on the top floor of the building, based on the feedbacks of the structure. the responses of the structure equipped by stmd are compared with those of the building with passive tuned mass damper (tmd) and the uncontrolled structure. the results showed an appropriate performance of the fuzzy controller in reducing the both translational and torsional responses of the rc building structure under the earthquake excitation.
