This document presents a comparative study on the seismic behavior of different shaped reinforced concrete (RC) structures equipped with viscous dampers. Three models are analyzed: H, T, and L shapes. The models are analyzed using ETABS software according to Indian seismic code provisions. Parameters like base shear, natural period, storey stiffness, drift, overturning moment, and displacement are compared. Material and geometric properties are kept the same. All models are located in seismic zone 4 and subjected to dynamic analysis using the El Centro time history record. Results show that the H-shaped building experiences the highest base shear, while viscous dampers help reduce storey displacement in the structures.
