Analysis and Design of High Rise RCC Building with a Comparative Study of Vibration Controlling Damper - Numerical Investigation of Structural Response and Vibration Control

High-rise reinforced concrete RCC buildings are exposed to lateral actions due to wind and earthquakes. As building height increases, lateral displacement, inter-storey drift and floor acceleration become important response quantities. Supplemental energy-dissipation devices, including viscous fluid dampers VFDs, may be used to modify the dynamic response of building structures. This paper presents a comparative numerical study of a high rise RCC residential building modelled in ETABS. Two configurations are considered: a conventional building without supplemental dampers and a modified building incorporating VFD link elements. The comparison is intended to examine storey displacement, inter-storey drift and base shear under corresponding analysis conditions. The project model has shown a reduction in lateral displacement after the introduction of VFDs; however, the final magnitude must be established from verified, storey-wise ETABS output. The paper therefore provides the analysis framework and result tables to be completed using the actual building dimensions, damper properties, load cases and numerical results.
