Learn how to model a dog‑legged staircase in ETABS step by step using a practical, code-oriented approach that every civil and structural engineer can apply in real projects.
​

In this part‑1 video, you will understand the complete workflow of staircase modelling using the first (most beginner‑friendly) method, so that you never stay confused again about how to handle stairs in ETABS.
​

What you will learn
Concept of dog‑legged staircase geometry (flights, landings, waist slab, supports).
​
​

How to set levels / reference planes and create landing beams correctly in ETABS.
​

Step‑by‑step modelling of waist slab and landing slab as area elements.
​

How to replicate the staircase across storeys safely without modelling errors.
​

Basics of dead load and live load consideration for dog‑legged stairs and how the load is transferred to beams and columns.
​
​

Why this video is important
Staircase modelling is one of the most common doubts for civil and structural engineering students, site engineers and design engineers using ETABS.
​
​

Incorrect modelling can lead to wrong axial forces in staircase‑supporting columns and beams, so understanding the right method is essential for safe design.
​
​

Who should watch
Civil engineering students and beginners learning ETABS.

Structural engineers who are unsure how to model staircases or currently use only approximate loading methods.
​
​

👉 In the next part (Part‑2), the second, more advanced method of modelling the dog‑legged staircase will be explained, including refined load distribution concepts and alternative modelling strategies in ETABS.
