Comparative Study Of RC Building With And Without Dampers By Varying Heights Using E-Tabs

Abstract

Due to the fast growth of the population, multi-story structures are becoming more important. The fundamental issue with multi-story constructions is that they are sensitive to ground motion. The earthquake causes vibrating forces at the structure's foundation; as a result of these vibrations, the building experiences oscillations, which may severely destroy the structure. These oscillations become more pronounced as the structure's height rises, causing serious damage to large-scale facilities. Structures are intended to resist and withstand dynamic forces using a mix of strength, deformability, and energy absorption to protect them from substantial damage. Dampers are employed in high-rise structures in seismic zones to minimise vibrations caused by lateral stresses, such as strong winds and earthquakes, in order to prevent such catastrophic damage. RCC constructions of 10m, 20m, and 30m storeys are investigated in this research. The buildings have a rectangular form and are 20x45 m2 in size, with a seismic zone of V. E-Tabs software is used to analyse structures. For modelling of RC framed structures, the loading calculations were done according to code regulations, namely IS:1893-2002, IS:875(Part-III)-1987, and IS:456-2000. With and without dampers, the parameters of base shear, storey drifts, storey forces, and storey stiffness are investigated.
