How to calculate the reinforcing bar leg length
How the reinforcing bar leg length is calculated depends on the angle between the bar legs.
- When the angle is <= 90°, the length is measured to the extension of a leg along the outer edge
- When the angle is > 90 ° and <= 180 °, the tangential length is used
The leg lengths are calculated using Rebar Shape Manager, where
S1= straight portion of a bar for the first segmentS2= straight portion of a bar for the second segmentA1= bending angle measured between the extension of the first leg and the second leg. The angle is 0° if the second segment continues to the same direction as the first segment (the bar is straight)L1= leg length for the first reinforcing bar segmentL2= leg length for the second reinforcing bar segmentRS= bending radiusDIA= actual diameter of the reinforcing bar
