SEISMIC ANALYSIS OF FRAMED STRUCTURES WITH AND WITHOUT FLOATING COLUMNS

The multi-storey buildings in urban cities are required to have column free space due to shortage of space, population and also for aesthetic and functional requirements. In order to have more area for parking space and for other amities, concept of floating columns in multi-storey framed structure is becoming popular stability used structural integrity of such structures while resisting earthquake becomes critical. For this buildings are provided with floating columns at one or more storey. In this Equivalent static method, response spectrum and time history method were used for analysis in ETABS-2015. Software was used and structure was assumed to be situated in earthquake Zone III. And the parameters like Base shear, Storey drift, and Displacement were evaluated.
