Incorporation of the seismic response control system plays a vital role in structural engineering. Conventional method of structural design involves the higher flexibility and lower damping characteristics during the application of seismic loads which leads to inelastic deformation to an acceptable limit. Modern technique of seismic energy dissipation aims towards achieving stringent performance requirement. This paper aims towards analysis of structural response of the benchmark building with semi active damper namely magnetorheological damper. The magnetorheological damper work depends on the Structural Control Algorithm and Current input. G+5 Reinforced Concrete Building response is studied with a connection of large scale 200KN MR Damper (MRD) for three proposed numerical models, namely Kelvin Voight Model, Hyperbolic Tangent model and Maxwell Non-linear Slider model. The predictive ability of numerical models is analyzed for varying current. For simulating seismic application three earthquake data were considered, El Centro, Imperial Valley and Northridge. Numerical models of MR Damper are studied under varying current and exponential value. The comparison of displacement and base Shear of the structure response gives satisfactory response in the analysis.
