Bar Bending Schedule for Footing

Bar bending schedule (BBS) of an concrete footing provides the reinforcement details and the total steel quantity required for the footing construction. The BBS and quantity of steel reinforcement required for a simply isolated footing are calculated and explained by means of a workout example. Calculation of Steel Reinforcement For Isolated Footing The figure-1 below shows the cross-sectional plan and section of an isolated footing. The details of reinforcement used in the footing are calculated from the detailed drawing of the structure prepared by the designer. The structural drawing provides the reinforcement location and their specifications. Fig.1. Plan and Cross-Sectional View of an Isolated Footing Details Obtained from Structural Drawing Following details are obtained from the drawings and specifications: Length of Footing = X The breadth of Footing = Y The height of the footing (Thickness) = h The diameter of the Main reinforcement bars = d m The diameter ...
