MULTIPLE-STORY BUILDING WITH AND WITHOUT A FLOATING COLUMN: A COMPARATIVE STUDY

Department of Civil Engineering

Buildings with Floating Columns are a common element in contemporary multi-story architecture in metropolitan India. Such characteristics are very undesirable in buildings constructed in seismically active zones. The significance of clearly noting the existence of the Floating Column in the examination of building. Alternative methods involving stiffness balancing of the first and second storeys are offered decrease the irregularity caused by Floating Columns FEM analysis was performed on 2D multi-story frames using & without a floating column to investigate the structure's reactions to various seismic excitations varying frequency content while maintaining the PGA and time duration factor constant Roof's historical timeline For both frames, displacement, inter-storey drift, base shear, and column axial force are estimated Column that floats. The load distribution on the floating columns and the various effects due to it is also been studied in the paper. The importance and effects due to line of action of force is also studied. In this paper we are dealing with the comparative study of seismic analysis of multi-storied building with and without floating columns. The equivalent static analysis is carried out on the entire project mathematical 3D model using the software STAAD Pro V8i and the comparison of these models are been presented. This will help us to find the various analytical properties of the structure and we may also have a very systematic and economical design for the structure.
