Abstract
This third edition guidance document continues to look at the causes, effects, and risks of cracking in concrete. It occurs when tensile strain is greater than the tensile strain capacity of concrete. Considers design aspects such as estimating the magnitude of crack-inducing strain, how to control the size of cracks using reinforcement and ways to minimise risk. First published in 1992 as CIRIA R91 and updated in 2007 as C660 to take into account design to Eurocodes, this 3rd edition provides further clarity for design relating to BS EN 1992-3.
