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...
In the present contribution, an attempt is made to lay down the factors influencing the value of the ultimate bond stress τdu in a formula by a theoretical approach. The stress condition in the concrete around the bar is described by means of the model of a thick-walled cylinder subjected...

Effect of confinement using steel, FRC, or FRP on the bond stress-slip response of steel bars under cyclic loading The results of experimental investigation of the local bond stress-slip response of steel bars embedded in confined concrete and subjected to cyclic loadin... MH Harajli - 《Mate...
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...
Bond stress is the equivalent unit shear stress acting in parallel to the reinforcing bar on the interface between reinforcing steel bar and concrete. Due to the transfer of forces through bond stress, between the reinforcing rebar and ... UM Mahran 被引量: 1发表: 2013年 BOND STRESS-SLIP-ST...
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 ...
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...

In the process of pulling out, the bar is subjected to tension whereas the surrounding concrete is in compression. In case of a beam test, both the steel and surrounding concrete are in tension. Because of the change in stress state, the results of the bond stress obtained from pull-out ...
