Abstract

Dominant cracking models for flexural elements are mostly based on assuming that a virtual tie forms around the reinforcement and the resulting expressions are derived from this assumption. The main difference in existing code formulations is that present in EN 1992-1-1:2004 in which the bond term for crack spacing is affected by factor k2 which is equal to 0.5 for bending and 1.0 for tension. This paper shows this to be an oversimplification of the problem. An improved proposal is made to account for this effect. But cracking in flexure is different from cracking in tension in other ways. One of them is the effect of curvature on the increase of crack width with cover. It will be shown that this effect, accounted for only in the comments of MC 2010, is very significant. Also, evidence of the effect of bad bond or good bond conditions on crack spacing, affecting mainly flexural members, will be given.
