Title: Effects of Arrangement of Reinforcement on Crack Width and Spacing of Reinforced Concrete Members
Author(s): Bengt B. Broms and LeRoy A. Lutz
Publication: Journal Proceedings
Appears on pages(s): 1395-1410
Keywords: beam, craking, crack spacing, crack width, internal crack reinforced concrete, reinforcement, research
Abstract:Long tensile specimens reinforced with bars in various arrangements were tested. The crack widths and the crack spacings were measured at several stress levels. The simple method previously developed for prediction of crack width and spacing in members with a single bar was extended to apply to members with multiple bars.Short tensile members were also tested. Resin was injected into all specimens to examine the internal crack formation. Comparison was made of the crack widths found in other investigations with the values predicted by the simple method developed.
