Abstract
An experimental study to characterise the annular distribution of the mechanical properties throughout the cross-section of TEMPCORE® steel bars is presented. Thereafter a sectional fibre model, which allows obtaining s–e and fatigue curves of corroded steel, is described. The model is calibrated using an extensive experimental study of artificially corroded steel bars tested under cyclic and monotonic loads. Local pitting effects such as stress concentration, local bending or non-uniform mat...
