A Study On 3d Bim Modelling And Structural Analysis Of A G+4 Residential Building Using Revit And Etabs.

Abstract

This project presents the Analysis, Design, and BIM-based Modelling of a multi-storey G+4 reinforced cement concrete (RCC) residential building using advanced structural engineering and modelling software tools, including CSI ETABS, CSI SAFE, CSI Detail, and Autodesk Revit. The primary objective of this study is to develop an efficient and accurate structural system by integrating conventional design practices with modern Building Information Modeling (BIM) techniques.
The structural analysis of the building is carried out using ETABS, where the complete 3D model is developed by defining grid systems, material properties, and structural components such as beams, columns, and slabs. The structure is analysed under various loading conditions including dead load, live load, wind load, and seismic load in accordance with relevant Indian Standard codes such as IS 456:2000, IS 875, and IS 1893:2016. The software provides critical outputs such as bending moments, shear forces, axial forces, storey drift, and base shear, which are used for the safe and economical design of structural elements. The design of beams, columns, and slabs is performed using limit state design principles to ensure structural safety, serviceability, and durability. Foundation design is carried out using SAFE, where soil-structure interaction, bearing capacity, and settlement considerations are incorporated to design safe and stable footing systems. Reinforcement detailing is further developed using CSI Detail, which generates accurate bar bending schedules (BBS) and detailed reinforcement drawings, reducing manual errors and improving construction efficiency. The integration of ETABS, SAFE, CSI Detail, and Revit ensures a streamlined workflow from analysis and design to detailing and modelling. This approach significantly improves accuracy, reduces design conflicts, and enhances project efficiency. The study highlights the importance of BIM in modern construction practices by demonstrating its role in improving visualization, coordination, cost-effectiveness, and decision-making throughout the project lifecycle. Overall, this project emphasizes the adoption of integrated software tools and BIM technology for the development of safe, economical, and sustainable multi-storey residential b
