Experiments were conducted with reinforcement ratio and mix proportions as parameters in order to study cracking of concrete due to restraint of drying shrinkage. This report describes comparison studies of results of measurements on crack widths made over a period of one year, and proposes the method for analysis of cracking widths with the cracked portion as a bond spring model. The calculated crack widths and number of cracks are compared with experimental values.
