Publisher's Synopsis
Cracking occurs when the tensile strain, arising from either restrained contraction or the strain differential within the concrete section, exceeds the tensile strain capacity of the concrete. Autogenous shrinkage also contributes to early contraction and drying shrinkage and annual temperature variations are added to early age effects over the long term. This guide provides a method for estimating the magnitude of crack-inducing strain and the risk of cracking at both early age and over the long term. Where cracking is predicted, guidance is provided on the design of reinforcement to control crack widths.
