👉Effective Depth (d) Requirements
💫The Effective Depth (d) is a calculated value, not a minimum requirement, and is used directly in all strength equations.
🚧1. Calculation of Effective Depth
⏺The effective depth is calculated based on the overall geometry of the section:
❇️d = D - Effective cover
🎲Where D = overall depth of the member
🔰Effective Cover = Clear Cover + Stirrup/Link Diameter + (Main bar Diameter) /2
📍To prevent noticeable deflection, the calculated L/d ratio must be less than the modified basic ratio.
⏺For example, for a simply supported beam with a 5m span, the minimum effective depth required for deflection control would be:
🌟d min =span/20 = 5000mm/20 =250 mm
