PROJECT OVERVIEW

📋 About the Project

Complete structural analysis & design of a commercial building

This project, completed during the Final Year of B.E. Civil, involved the complete structural modeling, analysis, and design of a multi-storey commercial building located in a high seismic zone. The objective was to ensure the structure meets seismic performance requirements, adheres to design standards, and demonstrates safe behavior under gravity and lateral loads.

STRUCTURAL MODELING

🏗️ Modeling & Structural Configuration

Accurate 3D analytical model in ETABS

✓ Detailed 3D analytical model in ETABS with accurate geometry
✓ Assigned beam, column, slab, shear wall properties per IS 456
✓ Storey levels, diaphragm constraints, mass distribution for dynamic analysis
✓ Prepared structural drawings in AutoCAD for verification
