Analysis of RCC Structure with Viscous Damper under Seismic Loading

Abstract

Generally dampers are the energy dissipating devices which resist displacement of reinforced concrete building during earthquake. As a tall building keep becoming taller, they becoming more susceptible to dynamic excitations such as wind and seismic excitation. For the structure safety and occupants’ comfort, the vibrations of the tall buildings are serious concerns for structural engineer. The damper helps the structure to reduce buckling of columns and beams also increases the stiffness of the structure. In this work a building with seventeen floors is analyzed with viscous damper at different levels and floors to reduce the vibrations and lateral sway of building. The building is analyzed according to their locations. Modelling, analysis and design of reinforced concrete structure shall
be done in ETAB software to obtain the displacement, storey drift of building with different magnitudes of earthquakes.
