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.
