ANALYSIS OF A BUILDING CONSIDERING FLOATING COLUMN UNDER LATERAL LOAD CONDITION USING ETABS

Columns rest on the beam without foundation are called floating column. They are used commonly in multi-storey buildings which are purposed to hold parking at ground floor or open halls at higher floors. Discontinuation within the load transfer path is seen in this column. Thus they are designed for gravity loads. But these structures aren’t designed for earthquake loads. In present scenario structures with floating column may be a common characteristic in urban India. However in tectonic areas, this type of structure is not preferred due to discontinuity of load transfer path i.e. whole earthquake load on the structure is shared by the shear walls without any loads on the floating columns.
