Bond slip relationship is very important to the study of the bond behavior of steel bars and concrete. For presenting the accurate bond slip relationship, the equations of stress of steel bars, bond stress, and relative slip of steel bars and concrete were deduced through theoretical analyses at...
Bond Stress Equation for Unconfined ConcreteThe purpose of this experimental work is to develop an equation for bond stress of unconfined concrete. The parameters considered in this study are content of silica fume, diameter of pull out bar and embedded length of pull out bar. Cubes and ...

The proposed model has been incorporated into the Vulcan program for 3D analysis of reinforced concrete structures in fire. The second robust model has been developed to predict the bond stress-slip relationship between the strand and concrete of prestressed concrete structural members. In this model...
Degradation of bond strength due to corrosion of steel strands is of great importance for serviceability of prestressed concrete structures. An analytical model is proposed to demonstrate the effect of corrosion of steel strand on reduction of bond strength. Corrosion expansion force generated by steel...
The NSM FRP strip is thought to be pulled out when the principal tensile stress of concrete on this semiconical surface exceeds the tensile strength of concrete. The method is able to consider the effect of groove spacing (i.e., the “interaction among adjacent strips” in their papers) on...
However, an even more significant change was observed with change in concrete cover. We also observed an effect of steel fibre inclusion. Inclusion of a 1% volume fraction of steel fibre increases the ultimate bond stress by two times the bond stress between the plain RPC matrix and ...
Bond-slip-strain relationship of deformed bars embedded in massive concrete. This model includes the effect of bar diameter and concrete strength. In the case of condition that the strain is zero where slip is zero, the bond stress can be expressed only by the slip. The bond-slip relationship...
The longitudinal variation in the bond stress in the GPC beams during the pull-out tests was calculated and plotted, as well as the stress in steel bars. The cracks on the bond area of the GPC were compared with those of the corresponding ordinary Portland cement concrete (OPC), as well ...
