How to calculate the cutting length of spiral stirrups(ring
The cutting length of the helical stirrup or spiral stirrup = n√C 2 + P 2 = 122 × √ 2.017 2 + 0.15 2 = 122 × √ 4.068 + 0.0225 = 122 × √ 4.091 = 122 × 2.023 = 246.76m. To get the exact cutting length of the spiral stirrup bars, we have to add lap length, as the length of an individual bar is limited to 12m.
