Physical and numerical models for the shear load-carrying capacity testing of steel-concrete bonded joints

Owing to the very good adhesion between epoxy resins and steel or concrete it is quite possible to achieve coupling of these materials by means of bonding alone, without using any additional coupling means such as anchors or dowels. The shear-bearing capacity and properties of such joints, from the point of view of their practical application, are the subject of the investigations reported. For the tests done in this work, physical models were designed by which it was possible to determine the stress distribution and approximate values of the shear-bearing capacity as a function of properties of the coupled materials. The concept of the physical models used was tested by numerical models.
