Considering equilibrium and compatibility conditions, the anchorage strength can be calculated on the basis of the local bond-slip relationship. Using this approach with the bond-slip relationship of MC2010, the obtained anchorage strengths are not consistent with the anchorage resistance according to the same code. Recent works have shown discrepancies between measured local bond-slip responses and the proposal of MC2010. Within this frame, this paper presents an experimental programme consisting of pull-out tests instrumented with detailed measurement systems (digital image correlation and fibre-optic measurements). The results show the effect of the evaluated parameters in the local bond-slip relationship along the bar. The different local bond-slip responses can be explained by the crack development in the surrounding concrete.bondrebar-to-concrete interactionanchorage resistancelocal bond-sliprelationshipsplittingspallingtext::conference output::conference paper not in proceedings
