vulnerability, causing the shear failure to occur progressively earlier. In contrast, the fibre model analysis confirmed that the flexural capacity remains sufficient and is not significantly compromised by degradation. Finally, the study showed that even the stronger (Y) direction is susceptible to a brittle shear failure, albeit only at advanced degradation levels.
