stress-to-crack width relationship for sound concrete. The stress–strain relationship corresponding to the stress-to-crack width relationship was derived using the modulus of elasticity (Ecm) and assumed crack band-width (h). In determining the crack bandwidth for the weakened ele-ments, localisation within one element row was assumed.

On modelling level 3, the bond between the concrete and reinforcement is modelled with a 1D bond stress–slip rela-tion, similar to level 2. The structural model is a three-dimensional (3D) FE model with continuum elements for the concrete and beam elements for the reinforcement. This enables explicit incorporation of pre-existing cracks into the

Correlation of Surface Cracks of Concrete due to Corrosion ...

The current experimental study presents the results of bond strength loss (steel bar concrete) due to the corrosion damage of steel bar specimens, semiembedded in concrete, at various times of exposure to corrosive environment. In this case, a correlation was made between the width of the surface cracks of concrete caused by reinforcing steel corrosion and bond strength for different distances ...

Sep 02, 2021  In the crack width range observed in RC and SFRC50 tension ties (0.06 mm ≤ w ≤ 0.24 mm), no relationship between crack width and either pitting depth or length of corrosion zone was observed. Since this range of crack widths is representative of real structures, it allows remarking that the level of corrosion in a structure can hardly be ...

It is believed that there is a strong correlation between the level of frost damage and the dynamic modulus of elasticity (Petersen et al. 2007, Zandi Hanjari et al. 2009b, Zandi Hanjari et al. 2009a).
