How to Calculate Cutting Length for Circular Stirrups | Afroz Civil How to Calculate Cutting Length for Circular Stirrups (Step-by-Step) In RCC construction, accurate cutting length of circular stirrups is essential for proper reinforcement detailing, cost control, and smooth site execution. This guide explains the cutting length calculation for circular column stirrups with a clear and practical example. Given Data Diameter of circular column (D) = 900 mm Clear cover = 40 mm Diameter of stirrup bar (d) = 10 mm Shape = Circular stirrup Hooks = 2 hooks (standard) Bend Criteria (As per Site Practice) 45° bend = 1d 90° bend = 2d 135° bend = 3d Standard hook length = 10d Where d = diameter of stirrup bar. Step 1: Effective Diameter of Stirrup (D 1 ) D 1 = D − 2(Clear Cover) − 2(Half stirrup diameter) D 1 = 900 − 2(40) − 2(10/2) ...
