SEISMIC PERFORMANCE OF RC BUILDING WITH FLOATING COLUMN

A floating column, also known as a hanging or stub column, is a vertical structural element that rests on a beam or slab without direct support from a foundation. Unlike traditional columns that transfer loads directly to the foundation, floating columns act as point loads on the supporting beam, which then transfers the load to the columns below. This design is commonly employed in multi-storey buildings to create open spaces on lower floors, facilitating uses such as parking areas, lobbies, or large halls. The beam supporting the floating column, known as a transfer or girder beam, must be designed to handle the concentrated load, often requiring increased depth and reinforcement. In the present scenario various multistory building are constructed with floating column at various locations for appealing view, for getting more space in parking area for movement and for planning of different plan at different stories. This paper present comparative study about analysis of G + 7 story building with and without floating column at various location within the floors for periphery columns at various levels for seismic zone . The motive of this paper is to compare the response of RC frame buildings with and without floating columns under earthquake loading and under normal loading. This study is to find whether the structure is safe or unsafe with floating column when built in seismically active areas.
