Analysis and Design of G+15 High-Rise Residential Structures with and Without Floating Column in Nepal

As large populations accommodate in the same building, the parking issue is common in many high-rise buildings. This study approach solves the same constraint by opting for floating columns on the ground floor to facilitate ample space between columns for parking. This project deals with planning, analyzing, and designing a high-rise residential building with and without floating columns. Detailed planning was done in AutoCAD software. On analysis under various load conditions in STAAD.Pro V8i software for both conditions one with a floating column and one without a floating column. A comparison is made on axial forces, shear forces, bending moment, and displacement in a selected few columns and beams in situ the structure. The study found a slight increment in axial force, shear force, bending moment, and displacement on opting floating column. Finally, critical structural elements—slab, beam, column, staircase, and foundation—are designed manually as per Indian Standard codes using maximum STAAD Output for both buildings. In manual designing, it is observed that a building with a floating column requires a slight increment of reinforcement to overcome safety constraints. Hence, this study concludes that floating columns can be opted for high-rise buildings by increasing the reinforcement percentage in structural elements.
