| Description |
The present study is limited to these dampers subjected zero voltage input, and the nonlinear force-velocity relationship of the same is obtained from experimental study. The model is subjected to two types of synthetic earthquakes and its base shear, acceleration, inter-storey drifts and displacements are found by non-linear time history analysis using SAP 2000. The reduction in maximum displacement, storey-drift, acceleration and base shear shows the effectiveness of non-linear VFDs with upper toggle brace configuration in 3-storey SMRF model over other types of placement of dampers such as chevron and diagonal bracings. The results show that provision of non-linear VFDs with toggle bracing mechanisms at ground floor level, would act as vibration control devices by dissipating energy at ground floor level where they are placed and controlling the vibration levels of floors above.
