Cracking of concrete structures due to imposed strains with regard to design of reinforcement
Abstract The principles for control of cracking in concrete structures due to imposed strain are investigated in this paper. The effects of uniform and non-uniform cooling and shrinkage are studied in medium-thick walls with regard to the amount of reinforcement necessary to distribute cracks. The influence of reinforcement on the behavior after the first crack is investigated, in particular its ability to reduce crack widths. The restraint force is significantly reduced for non-uniformly distributed imposed strain due to softening and cracking in the concrete. The amount of minimum reinforcement needed to distribute cracks is therefore significantly smaller for imposed strain in the form of drying shrinkage than for thermal imposed strain. Crack reinforcement is most effective for structures with large dimensions in the direction of external restraint.
