Title: Stress Development of Tension Steel in Beams
Author(s): Raymond E. Unitrauer and George E. Warren
Publication: Journal Proceedings

Abstract:Data on the effect of bar spacing and beam width was obtained by testing 27 beams consisting of 22 top bar and 5 bottom bar tests. The results show that bar spacing and width are very important variables in the amount of stress that can be developed in the tension steel. An equation to determine the amount of steel stress that can be developed was derived. Stresses computed by this equation are in good agreement with the experimental stresses.
