Abstract

The Dynamic response of a multi-storey asymmetrical space frame structure having six degrees of freedom (three translations along x, y, z – axes and three rotations about these axes) at each node, with multiple tuned mass dampers (MTMD) on its top is studied. MTMD with uniformly distributed frequencies are considered for this purpose. The effect of damping ratio of the dampers on the effectiveness of MTMD is also studied. It is found that the MTMD are more effective than a single TMD in reducing the translation and rotational response of multi-storey asymmetrical space frame structure. It is also observed that there exists an optimum value of damping ratio of the damper at which the response of the structure becomes minimum for both single TMD and MTMD
