Description
The models for crack width control in the elements where cracking is caused by the restraint of imposed strains are adopted from the models for the elements under direct tension. The practice has shown, however, that the general models for crack width control do not always correctly predict the crack width when cracking is caused by the restraint of imposed strains. This results from the fact that by using these calibrated models their predictive capacity decreases as the characteristics of the analysed structure deviate from the characteristics of the elements in the calibration database. This work discusses peculiarities in crack width estimation is special structures, characterised with untypical features, such as high massivity, low degree of reinforcement or large concrete cover.
