Bar Bending Schedule (BBS)

Generate BBS tables with cutting lengths, bend deductions (IS 2502), lap lengths, and weight calculations. Add multiple bar groups and export the complete schedule.

πŸ“ Bend Deduction Reference (IS 2502)
45Β°
1 Γ— d
d = bar diameter
90Β°
2 Γ— d
Most common bend
135Β°
3 Γ— d
Seismic hook
180Β°
4 Γ— d
Full U-hook
Hook Length: 9d per hook (IS 456 Cl. 26.2.2.1) for 180Β° semi-circular hook.
Lap Length: Ld = (0.87 Γ— fy Γ— Ο†) / (4 Γ— Ο„bd) per IS 456 Cl. 26.2.1. Deformed bars: multiply bond stress Γ— 1.6.
