Title: Calculating the Length of Bent Reinforcing Bars
Author(s): Dick Birley
Publication: Concrete International
Appears on pages(s): 63-65
Keywords: bend deduction; bending reinforcement; constructibility; fabrication
Abstract:When fabricating bent reinforcing bars, the cut length of the initially straight bar must account for fillets created at the bend points. Ordinarily, these bend deductions can be obtained using simple geometric calculations. However, when extremely tight tolerances are required, the behavior of the bar as it’s bent around the mandrel must also be taken into account. The factors affecting the behavior of the bar and a method of empirically determining bend deductions for these conditions is discussed in this article.
