In reinforced concrete structures, it is extremely difficult to ensure that steel
bars will be not subject, either in a lower or higher extent, to the corrosion effect. The
application of hot dip galvanized rebar is an economic and effective way of protecting
reinforced concrete against corrosion. This protective technique has an influence, which
should not be disregarded, on the performance of the rebar’s coating, its behaviour and,
fundamentally, the bond between concrete and galvanized rebar. With the aim of studying
the bond behaviour between galvanized steel rebar and concrete, an experimental
program was carried out by means of direct pullout tests. To predict the full pullout
response, an analytical cohesive interface model was developed to obtain the bond stressslip
relationship. To account for the interfacial bond, a nonlinear bond stress-slip law was
used. In the present work the numerical method and mathematical tools are detailed and
its performance is assessed. Hence, the parameters that define the local bond stress slip
relationship are obtained by a fitting procedure between the simulated pullout curve and
the experimental one. Finally, the obtained local bond law relationship is compared to the
one proposed by the CEB-FIP Model Code
