Abstract:
A method to forecast bond stresses by accounting for tension transmitted across radial cracks is presented. This phenomenon is known as cohesive cracking. When steel and uncracked concrete are present they are treated as isotropic materials. Concrete however behaves as an anisotropic material after radial cracks develop. Several factors are identified as parameters influencing bond stresses. Among them axial force in steel, area of the bar, concrete strength, and confinement are important. Results based on proposed method are discussed under a variety of practical situations.
