Abstract
A structure in high seismic regions must perform under large forces without failing; hence, in this scenario, inelastic energy dissipation plays an important role in resisting large forces mainly caused by an earthquake. A ductile structure can deform and dissipate energy during an earthquake because it keeps deforming without reaching ultimate failure or collapse. In this study, the ductility of mid-rise RC buildings was compared under high seismic zones for different aspect ratios. Investigations were performed by following the Indian standard code with respect to plan aspect ratios. Reinforced concrete buildings with 10, 20 and 30 stories were modelled using five different plan aspect ratios of 1:1, 1:2, 1:3, 1:4, 1:5 and 1:6 under two categories, viz., category 1 with different plan aspect ratio and category 2 with the same plan area. The buildings were analysed by employing response spectrum and non-linear static analysis to obtain the results using Etabs software.
