Bar Bending Schedule (BBS) Calculator
Quality Inspector
A comprehensive tool for calculating the Bar Bending Schedule. Input multiple bar shapes, diameters, and lengths to find the total reinforcement budget.
📐 Formula & Method
Cutting length is Span - (2 * Cover) + Hook additions - Bend deductions. Total weight = Cutting Length * D^2/162.2 * Quantity.
Cutting Length = Span - 2(Cover) + Hooks - Bends
📋 Worked Example
Straight bar in 5m span, 25mm cover, 12mm dia: • Length = 5000 - 50 = 4950mm = 4.95m • Weight = 4.95 * 0.888 = 4.39kg
