This study examines the seismic performance of high-rise building structure in Seismic Zone IV using STAAD Pro V8i, comparing structures with and without floating columns. The analyzed building has 11 stories, a height of 33.8 m, and a floor plan of 18.92 m × 19.78 m. It consists of 50 columns, 12 of which are floating, supported by beams on the second level instead of extending to the foundation. Shear walls are used to support these columns and transfer loads to the underlying structure. Both structures share identical height, configuration, and loading parameters. This study evaluates key factors, including beam moment, shear force, nodal deflection, concrete volume, and steel usage. Results show a minor difference in concrete consumption (654.6 CUM for floating columns vs. 666.4 CUM without). However, integrating floating columns with shear walls significantly reduces maximum displacement and inter-story drift, enhancing the structure’s seismic performance. These findings highlight the potential benefits of floating columns when combined with shear walls in high-rise building design.
