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.
