What You'll Learn in this video:
1️⃣ A quick recap of what development length (Ld) is and why it’s essential for structural integrity.
2️⃣ How to use the Excel sheet I’ve created, designed for both compression members (columns) and tension members (beams/slabs).
3️⃣ Step-by-step examples for calculating development length for columns and beams using real-life data.

How to Use the Sheet:
✅ Input these three values in the yellow cells:

Grade of steel (Fe 415, Fe 550, etc.)
Grade of concrete (M20, M25, etc.)
Diameter of the bar
✅ The Excel sheet will instantly calculate the required development length for your structural element.

Example Calculations in This Video:

Column: Fe 550 steel, M25 concrete, 20 mm bar → Result: 860 mm (43d)
Beam: Fe 415 steel, M20 concrete, 16 mm bar → Result: Automatically calculated!
