Analysis and Design of a G+4 Reinforced Concrete Residential Building Using ETABS

Abstract

The structural design of low- to mid-rise residential buildings in urban areas requires reliable assessment of gravity and lateral load effects, appropriate member sizing, and code-compliant detailing of reinforced concrete elements. This paper presents the analysis and design of a G+4 reinforced concrete residential building modelled in ETABS. The building was idealized as a reinforced concrete framed structure with five storeys, 3.0 m storey height, M30 concrete, Fe500 reinforcement, 150 mm slab thickness, 400 mm x 500 mm beams, and square and rectangular columns of 450 mm x 450 mm and 350 mm x 450 mm, respectively. Loads were assigned in accordance with Indian code provisions for dead, imposed and wind loads, and the frame was analysed for displacement, shear force, bending moment and axial force response. The results indicate that the adopted member sizes are structurally adequate for the considered G+4 residential configuration under the applied load cases, subject to final validation using project-specific soil investigation data, seismic parameters and detailed construction drawings. The study demonstrates the usefulness of ETABS as an integrated modelling, analysis and design environment for reinforced concrete building systems, while emphasizing that software results must be supported by engineering judgement, code checks and quality control during execution.
