Tuned Mass damper set is one of the tools of passive energy dissipation . This means the amount of energy absorbed by the dynamic loads to the structure , the demand for energy dissipation in the main structure decreases . For this purpose set the only mass damper efficiency (TMD) and damper efficiency multiple set offense (MTMD) with two types of parallel and series, all with the distribution of the percentage of 2% was designed and Jeremy effect different makeup this mechanism in improving seismic behavior of structure under earthquake excitation three types were studied. For modeling of shear frame structures from a ten floors with the linear behavior of the interest taken and equations of motion of structures equipped with control mechanisms has been extracted and the response of structures under vibrational input about the three evaluated. The only damper efficiency mechanisms Jeremy and effective in the reduction of multiple structural responses and parallel between them fairly on the reduction mechanism of( MTMD) structural response more effective. It is also the perfect makeup for all of the above mechanisms installed in the upper classes of structures.
