Type each beam's support length (l), distance of the fracture line from the nearer support (a), width (b), depth (d) and load, or leave the sheet empty to print a blank format. Flexural strength (IS 516) = P l / (b d²) when the fracture is within the middle third (a ≥ l/3, or a left empty), and 3 P a / (b d²) when a is just outside it (a ≥ 170 mm for 150 mm beams on 600 mm span, 110 mm for 100 mm beams on 400 mm span); below that the result is marked “Discard”. Set and overall averages are worked out as you type. Typed values are saved for this project.
