Abstract:
The influence of concrete strength on the thermally induced stresses during curing of three large columns was investigated. Heat flow analyses, adjusted to match the measured temperatures, enabled the temperature distributions to be determined. Finite element analyses were carried out to investigate the risk of cracking due to stresses induced by the nonlinear thermal strains. The higher strength concretes did not result in larger maximum temperatures and had lower risks of cracking than the normal strength concrete used.
