This document summarizes the analysis and design of G+3 and G+25 storey reinforced concrete frame buildings according to Indian standard codes. Loads including gravity and lateral loads were applied according to relevant IS codes, and the structures were analyzed and designed using ETABS software. Various checks were performed to ensure the structures met code requirements and did not experience instability. The objectives were to generate accurate models and conduct analysis and design without failure or instability using static and dynamic methods outlined in the IS codes.
