Integrated BIM Workflow for Structural Modeling, Analysis, and Design of a G+30 Reinforced Concrete Building Using Autodesk Revit and ETABS

Abstract

Building Information Modeling (BIM) can reduce fragmentation between structural modeling, analysis, design and documentation, but the practical transfer of analytical information between BIM and structural analysis platforms remains a critical workflow issue. This study develops and evaluates an integrated BIM workflow for a Ground plus Thirty (G+30) reinforced concrete building using Autodesk Revit and ETABS. A parametric three-dimensional structural model comprising grids, levels, reinforced concrete columns, beams, slabs and foundations is developed in Revit. The analytical representation is transferred to ETABS, where gravity, wind and earthquake actions are considered and reinforced concrete members are designed in accordance with the Indian Standard provisions adopted in the project. The reported numerical response includes a maximum roof displacement of 128.4 mm, maximum inter-storey drift ratio of 0.0019, base shears of 18,960 kN in X and 18,340 kN in Y, and modal periods of 3.52, 3.28 and 2.87 s for the first three modes. The study reports satisfactory flexural, shear, deflection and reinforcement performance for beams, columns and slabs. From the BIM perspective, structural geometry was transferred successfully, most member properties were retained, minor analytical connectivity adjustments were required, and subsequent design revisions and quantity schedules remained synchronized. The study demonstrates that Revit–ETABS interoperability can support an integrated digital structural workflow while emphasizing the need for post-transfer model verification.
