Abstract

The article presents a detailed comparison of two calculation models with Eurocode Standard guidelines. The stress has been put on defining the amount of reinforcement necessary to reduce the width of cracks resulting from imposed deformations in various ambient conditions. With the help of dierent approaches, the article presents the influence of the atmospheric factor on crack occurrence and crack width. Moreover, the calculation results are compared with the actual cracking during experimental investigations of RC tank wall segments. Adopting this approach it was possible to evaluate the eciency of calculation models pertaining to the analysis of the influence of imposed deformations on cracking in maturing concrete. The way of crack calculation defined in Eurocode Standard, in case of tank walls concreted in the first stage, leads to underestimating crack width in comparison with the crack width observed during experimental investigations.
