Comparative study between structure with and without a fluid viscous damper under seismic excitation

The effect of fluid viscous damper on the seismic response of building is investigated. Although buildings without fluid viscous damper have a disadvantage in increasing damage to the superstructure under earthquake. The influence of fluid damper in controlling the responses of building is investigated using a multi-storey building frame. Analysis is carried out using ETABS software. The seismic responses are compared with that of the building without and with passive fluid viscous damper. Based on the results, it is concluded that fluid damper is beneficial to achieve reduced the deformation of the superstructure. it is concluded that the distribution of fluid viscous damper in building is the most effective in reducing the base shear forces without significant increase in superstructure forces.
