Dynamic Analysis of Steel Frame Using Manufactured Viscous Damper

A five storey single bay steel moment resisting frame with manufactured viscous damper is analyzed for Bhuj earthquake acceleration data of January 26, 2001 using SAP 2000v14.0 analysis tool. Six different steel frame model is set up in which placement of damper is varied. Time history analysis was carried out and the output parameters like displacement, velocity, acceleration and base shear were tabulated and graphical results were also obtained. The results showed that the steel frame performed better when manufactured viscous damper is placed on all the floors as there is larger reduction in the drift, velocity, acceleration, but larger increase in base shear.
