ABSTRACT
This research includes experimental and analytical studies that revealed the mechanisms of the shear stress distribution along the adhesive-concrete interface of epoxy adhesive anchor fixed with a short embedded length (L=50 - 100 mm) and different diameter of the fixing hole (D=14 - 40 mm). The averaged shear rigidity was calculated with FEM that could be a representative value of all the adhesive layers and their adjacent interfaces. The achieved shear rigidity was used to compose a macro model based on the shear-lag theory. Its model enabled to make simulations with varied shear rigidity of the adhesive layer, finally finding the relationship between the interface properties and the shear stress distribution at the interface.
