Title: A Guide for Determination of Bond Strength in Beam Specimens
Author(s): ACI Committee 408
Publication: Journal Proceedings
Appears on pages(s): 129-136
Abstract:This report of ACI Committee 408, Bond Stress, was prepared to serve as a guide for the design of bond test beams and the choice of test procedures suitable for the determination of bond values of reinforcing bars. Although the Institute Standard ACI 208-58, specifies in complete detail the beam specimens and the test procedures to determine the relative bond values of reinforcing bars, it limits the bars to one size, concrete to one strength and the embedment length to a maximum of 16 in. The guide is intended to provide greater flexibility in the recommended test specimen and test procedure to permit the use of bars of different diameters, more than one strength of concrete, and longer embedment lengths needed to develop high yield strengths of modern deformed bars. The methods of support and measurement of slip are also different from those in ACI 208-58.
