Within the suggested configuration, various investigation parameters can be facilitated, such as the variation of concrete properties, interface roughness and number of transverse dowels. The specimen consists of three distinct concrete blocks in contact, as to create symmetric double interfaces. The middle concrete block has different concrete compressive strength, which suggests interfaces cast in different times. For the specimen preparation, elaborate computer-aided manufacturing (CAM) methods such as 3D design, laser-cutting and CNC-milling have been utilized. Moreover, an ad-hoc numerical analysis is performed, in the form of a blind-test procedure against its forthcoming experimental counterpart. The analysis is based on a three-dimensional nonlinear finite element model, accurately describing the physical specimen properties and loading setup. The analytical results are presented in a form of interface shear stress vs. slip, stress variation contours along the interface area and dowel tensile stress. A comparison with Code-based recommendations is performed and various interesting points are highlighted.
