Fluid viscous dampers were used in a 1/3 scale three story steel structure to dissipate seismic energy. The
geometric configuration of the supplemental damping was design such that it did not alter the shear and axial demand on
columns. In addition, it used less width and height of the span and allowed space for architectural openings. A lever
mechanism technique was used for this purpose which used comparatively smaller sized dampers. The results obtained
after the experimental testing indicated approximately 48% reduction in both acceleration and drift.
