How to calculate the reinforcing bar leg length

How the reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure

The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.

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
