further increase in the shear force has no apparent influence on stress at the hinges. The

distance between the hinge points reduced with increasing strength of concrete. The strength of the concrete greatly affects shear displacement and bolt contribution. However, no significant change was observed in the induced stresses beyond the yield

There was an exponential relationship between the shear stress and distance from the

 The shear stress was not exceeded during further loading after the yield point. Eventually, a combination of this stress with induced tensile stress at the bolt - joint

Shear stress at the bolt - joint intersection increased slightly with an increasing strength

There was no significant change in the hinge point distances with an increase in bolt

There was a significant increase in shear displacement beyond 35% of the loading step,

 The strain in the shear direction along the concrete was reduced (around 15%) with increasing the pre-tension loading. In both axial and shear directions the strain

The induced stresses exceeded the uniaxial compressive strength of the grout near the

The damaged area in the upper side of the grout was approximately 60 mm from the

Induced stress along the grout was reduced by increasing the pre-tension load nearly

The strain was decreased by around 3% and 5% in the compression and tension zones

Failure of the bolt - resin interface occurred by the grout shearing at the profile tip in

 Numerical simulation provided an opportunity to better understand the stress and strains generated as a result of the bolt - resin interface shearing. Such an understanding

Findings from the experimental test agreed with the numerical simulations and

The maximum shear stress was concentrated near the bolt - joint intersection.
