How do you estimate stirrups?
Method for Calculating Cutting Length of Stirrup:
- Look at the size of column or beam from drawings.
- Adopt Dia of the bar (generally 8mm Dia is used for stirrups)
- Deduct the concrete cover or clear cover.
- Find the total outer length of stirrup after deducting concrete cover.

What is the maximum distance between stirrups?
Detailed Solution. As per IS 456:2000, the spacing between two successive stirrups in reinforced concrete beam shall not be less than 100 mm. Maximum size of the bar or whichever is greater.
How do you calculate stirrup spacing?
spacing of stirrups in beam formula According to cl. 26.5. 1.5 of IS 456, the maximum spacing of the stirrups = 0.75 d = 0.75 (450) = 337.5 mm = 300 mm (say). So, we select 10 mm, 2 legged stirrups @ 145 mm c/c.
