This study emphasises the importance of explicitly recognising the presence of the floating column in the analysis of buildings, as floating columns are a common feature in modern multistory construction in urban India, but they are highly undesirable in buildings built in seismically active areas. Alternative measures, involving stiffness balance of the first storey and the storey above, are proposed to reduce the irregularity introduced by floating columns. FEM codes are developed for 2D multi storey frames with and without floating column to study the responses of the structure under different earthquake excitation having different frequency content keeping the PGA and time duration factor constant. The time history of floor displacement, inter storey drift, base shear, overturning moment are computed for both the frames with and without floating column.
