Title: Effect of Type of Bar on Width of Cracks in Reinforced Concrete Subjected to Tension
Author(s): David Watstein and Norman A. Sees, Jr.
Publication: Journal Proceedings
Appears on pages(s): 293-304
Abstract:Eight types of reinforcing bars were tested to determine the effect of various kinds of deformations on width of cracks in reinforced concrete subjected to tension. The effect of repeated application of load on the width of cracks was also determined for two of the bars. The bonding efficiency of the bars was determined with a supplementary series of tensile specimens. For the most efficient type of bar, the width of cracks was less than 50 percent of that found for a plain round bar, when both bars carried a stress of 40,000 psi. A fair correlation was found between the width of cracks and the elongation at a given load measured in the tests of bonding effi-ciency. The width and spacing of cracks decreased, in general, with increasing on reinforcement bars. bearing area of lugs
