Abstract : Floating columns are commonly adopted in reinforced concrete (RCC) buildings to meet architectural requirements such as open ground floors and large unobstructed spaces. However, their presence introduces vertical irregularities that significantly affect seismic performance. This study evaluates the seismic response of a G+12 RCC building considering four structural configurations. Linear dynamic analysis using the response spectrum method is performed in accordance with IS 1893 (Part 1):2016. Key parameters such as storey displacement, storey drift, bending moment, shear force, and axial force are compared. Results indicate that inclined and ground-level floating columns significantly increase structural flexibility and force concentration. Exterior floating columns at higher levels show comparatively moderate impact. The study highlights critical configurations and provides design recommendations for safer adoption of floating columns.

Keywords : Floating Columns, Seismic Analysis, RCC Frames, Response Spectrum Analysis, Inclined Columns, Vertical Irregularity.
