“Comparative Structural Analysis of Multi-Storied Buildings Using Revit–Robot Integration, ETABS, and Manual Design as per IS 456” Sayeda Uruba Samrin Inamdar1, Shradha Hiremath2 1Post graduate student, Dept of civil Engineering, SGBIT college, Belagavi, Karnataka, India 2Assistant professor, Dept of civil Engineering, SGBIT college, Belagavi, Karnataka, India ---------------------------------------------------------------------***--------------------------------------------------------------------computational approaches and assumptions can be Abstract - The integration of Building Information Modelling

(BIM) with structural analysis software has improved the accuracy and efficiency of modern building design. This study focuses on a G+4 multi-storied reinforced concrete (RCC) building, modeled in Autodesk Revit and analyzed using Robot Structural Analysis and ETABS. The primary objective is to compare the results obtained from these software platforms with manual calculations performed as per IS 456:2000. The structural model was first developed in Revit, providing coordinated architectural and structural details, and then exported to Robot for analysis. A parallel model was analyzed in ETABS to verify consistency. Key parameters including bending moments, shear forces and axial loads were compared across all three approaches. The findings indicate close agreement between software results and IS 456 manual design, with minor variations due to algorithmic differences. This study demonstrates the effectiveness of BIM-integrated workflows while emphasizing the continued importance of manual IS code validation for ensuring structural safety and compliance.
To ensure reliability, the results of bending moments, shear forces, axial loads, and deflections from both software are validated against manual design calculations performed as per IS 456:2000. Manual design not only serves as a benchmark but also ensures compliance with codal provisions, which remain essential for structural safety. This comparative study highlights the effectiveness of BIMenabled workflows while demonstrating the continued significance of manual code-based validation in structural engineering practice.
2. LITERATURE SURVEY Building Information Modelling (BIM) is increasingly used for structural design due to its integration of architectural and analytical models. Ahmed et al. (2024) demonstrated BIM application through Revit and Robot Structural Analysis for a G+5 RCC building, improving accuracy and sustainability. Sampaio et al. (2019) highlighted BIM’s capability in generating analytical models and reinforcement details but noted interoperability limitations between Revit and Robot. Jebur (2020) modelled and analysed a G+5 building with Revit–Robot integration, emphasizing efficiency and validating results with IS 456:2000.

1.INTRODUCTION Building Information Modelling (BIM) has emerged as a transformative approach in the architecture, engineering, and construction (AEC) industry by integrating design, visualization, and analysis into a single framework. Among the available BIM platforms, Autodesk Revit plays a key role in developing coordinated architectural and structural models of multi-storied buildings. Its interoperability allows direct export of structural models to analysis software, enabling accurate assessment of structural behaviour under various loading conditions.
Other studies compared software like ETABS, STAAD.Pro, and Robot, showing variations in bending moments, shear forces, and deflections due to computational differences. However, all confirmed close agreement with IS code-based manual design, reinforcing the necessity of manual checks. Research on seismic behaviour of multi-storied RCC structures further demonstrated ETABS as a reliable tool for dynamic analysis. Overall, literature indicates that BIM-integrated workflows enhance accuracy and productivity, while manual validation remains critical for safety and compliance.
In this study, a G+4 reinforced concrete (RCC) building is modelled in Revit to establish a BIM-based framework for design and analysis. The structural model is analysed using Robot Structural Analysis, which is well-suited for integration with Revit, and also using ETABS, a widely adopted software for multi-storied building analysis and design. By evaluating the same structure across both platforms, differences in results due to variations in
