Extended Three-Dimensional Analysis of Building System (ETABS) (version19) is a powerful software, used for building analysis and design. This software used for analysis purpose to this study. The study in this paper mainly strengthens on overturning moment and eccentricity of I-shaped fifteen storied building in both equivalent lateral force method and modal response spectrum method. The analyses are carried out as per ASCE7-16 and BNBC 2020 guidelines. It is observed that the overturning moment is approximately 11% greater in equivalent lateral force method than modal response spectrum method while in eccentricity approximately 2% greater in modal response spectrum method than equivalent lateral force method.
