The bond behavior of reinforcing bars is an important determinant of strength and stability. The article "Experimental Study on the Bond Behavior of Reinforcing Bars Embedded in Concrete Subjected to Lateral Pressure"t reported the results of one experiment in which varying levels of lateral pressure were applied to 21 concrete cube specimens, each with an embedded 16 mm plain steel round bar, and the corresponding bond capacity was determined. Due to differing concrete cube strengths (f, in MPa), the applied lateral pressure was equivalent to a fixed proportion of the specimen's f (0, 0.1f.., 0.6f). Also, since bond strength can be heavily influenced by the specimen's f bond capacity was expressed as the ratio of bond strength (MPa) to vf. cu' cu Pressure 0.1 0.1 0.1 0.2 0.2 0.2 0.3 0.3 0.3 0.4 Ratio 0.123 0.100 0.101 0.172 0.133 0.107 0.217 0.172 0.151 0.263 0.227 0.252 0.310 Pressure 0.4 0.4 0.5 0.5 0.5 0.6 0.6 0.6 Ratio 0.365 0.239 0.365 0.319 0.312 0.394 0.386 0.320 (a) Does a…
