How the reinforcing bar leg length is calculated depends on the angle between the bar legs When the angle is lt 90 176 the length is measured to the extension of a leg along the outer edge When the angle is gt 90 176 and lt 180 176 the tangential length is used The leg lengths are calculated using Rebar Shape Manager where
To determine the length the following formula is used L n√C 2 P 2 here n denotes number of turns in the spiral bar C denotes circumference of the bar and P denotes pitch of the bar The value of n is determined with the following formula n H P Total Height of the column Pitch 10 2 5
