Seismic Analysis & Structural Design of a Commercial Building

Software Used: ETABS, SAP2000, SAFE, AutoCAD, MS office etc.
Codes Followed: IS 456:2000, IS 1893:2016, NBC 105, IS 875 (Part 1–2) etc.

Project Overview

This project was done in Final Year of B.E civil which involved the complete structural modeling, analysis, and design of a multi-storey commercial building located in a 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.

Modeling & Structural Configuration

  • Developed a detailed 3D analytical model of the building in ETABS using accurate geometry, member properties, and material parameters.

  • Defined and assigned beam, column, slab, and shear wall properties as per IS 456 and typical RCC building practices.

  • Created storey levels, diaphragm constraints, and mass distribution ensuring correct modelling for dynamic analysis.

  • Prepared structural drawings and model verification in AutoCAD.

Load Application & Load Cases

Applied all essential load patterns according to IS standards:

  • Dead Load (DL): Self-weight of structure, finishes, partitions

  • Live Load (LL): Imposed loads per occupancy

  • Seismic Load (EL): As per IS 1893 using response spectrum method

  • Floor Load & Wall Load Distribution applied accurately over structural elements

Created load combinations following IS 875 and IS 1893 recommendations, such as:

  • DL + LL

  • DL + EQx

  • DL + EQy

  • 1.2(DL + LL ± EQ)

  • 1.5(DL ± EQ)

Analysis Performed

  • Conducted static and dynamic seismic analysis, including Response Spectrum Analysis.

  • Checked storey drift, storey displacement, and base shear to ensure compliance with the code.

  • Verified load path, stiffness distribution, and torsional irregularities.

  • Evaluated bending moments, shear forces, axial forces, and deflection patterns for all structural elements using ETABS and SAP2000.

Design of Structural Components

Designed RCC elements according to IS 456 & IS 13920:

  • Slabs: One-way/two-way slab reinforcement design and detailing

  • Beams: Flexural and shear reinforcement design

  • Columns: Axial load–moment interaction checks and reinforcement

  • Footings: Used SAFE for isolated footing design, soil pressure checks, and punching shear analysis

  • Staircase & Foundation Components: Modeled and designed based on load distribution

  • Ensured all elements satisfied strength and serviceability criteria

Deliverables & Outputs

  • ETABS analysis model, structural diagrams, and load behavior visuals

  • Detailed design sheets for beams, slabs, columns, and foundations

  • AutoCAD drawings including layout plans, reinforcement details, and schedules

  • Comprehensive structural analysis report, including:

    • Load summary

    • Seismic performance results

    • Deflection and drift checks

    • Reinforcement detailing

    • Foundation design calculations

Key Learning & Contribution

  • Gained strong hands-on experience in seismic design methodology, dynamic analysis, and practical application of Indian and Nepalese codes.

  • Developed proficiency in model optimization, error fixing, and ensuring realistic structural behavior.

  • Strengthened understanding of analysis–design workflow, documentation, and preparing professional engineering reports.
