Seismic Analysis of Multistorey Building with Floating Columns

Buildings with floating column are highly undesirable to be built in seismically active areas since due to discontinuity in direct load path they have shown poor performance in the past earthquakes. This paper studies the nonlinear (pushover) analysis for G story normal and floating column buildings using the response spectrum specified in the IS code in SAP2000. Behaviour of building swith floating column identified and based on these findings some new system of floating column building swith different patterns of bracings and shear wall sare proposed to make the buildings with floating column safe in seismically active areas.
