Complete G+3 Building Design in ETABS using AutoCAD Plan | Modeling, Analysis & Design (IS Codes)

Описание: Master the complete Modeling, Analysis and Design of a G+3 residential building in ETABS using a real AutoCAD plan in this 1 hour 37 minute step‑by‑step beginner‑friendly tutorial.​

What this video covers
Creating a new ETABS model from scratch: grid setup, storey data, material definition (M25 concrete, HYSD 415 & HYSD 500 steel) and section properties for beams (200×300 mm), columns (300×400 mm) and 150 mm slab.​

Using an AutoCAD architectural plan inside ETABS for accurate beam, column and slab modeling, followed by model checking to remove connectivity and geometry errors.​

Loading and IS code basics
Defining and assigning all major load patterns: dead load, live load (LL = 2 kN/m²), floor finish and ceiling plaster (1.5 kN/m² thumb rule), wall load using density × thickness × wall height, plus wind and earthquake loads.​

Applying loads and restraints at supports, then generating load combinations as per IS 456:2000 along with IS 875 (Part 1 & 2) for dead and imposed loads, IS 875 (Part 3) for wind, and IS 1893:2016 for seismic loads.​

Analysis and result interpretation
Running structural analysis and reviewing deformed shapes (deflection), support reactions, moment diagrams, axial force diagrams and restraint reactions, along with elevation views of the full G+3 frame.​

Understanding how these results relate to serviceability and strength criteria, including deflection limits and basic stability checks as per IS 456:2000.​

Design check and optimisation
Performing frame design checks in ETABS, reviewing longitudinal reinforcement, rebar percentage and pass/fail status of beams and columns for the selected material grades and member sizes.​

Learning how to modify grade of concrete/steel and adjust member dimensions when elements fail, and re‑run design until the complete G+3 model satisfies code requirements and works smoothly.​
