Floating columns are widely used in modern multi-story buildings for architectural and functional benefits. However, their presence leads to load transfer irregularities, making buildings vulnerable in seismic conditions. This study investigates the seismic performance of reinforced concrete (RC) buildings with and without floating columns on both sloping and plain terrains. Using STAAD Pro V8i software, G+4 models were analyzed under seismic conditions. The study evaluates parameters such as natural frequency, time period, base shear, storey drift, displacement, and forces. The findings emphasize the importance of proper design considerations for floating columns, especially in seismic zones, to ensure structural safety.
