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 segment
- S2 = straight portion of a bar for the second segment
- A1 = 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 segment
- L2 = leg length for the second reinforcing bar segment
- RS = bending radius
- DIA = actual diameter of the reinforcing bar
