The article presents a study of the interface performance of precast prestressed composite beams. The main objective of the research program is to determine the influence of the interface's shape on the composite element's behaviour. The rib-shaped precast prestressed beams with full bond, broken adhesion and broken contact were tested. DIC measurements with force-displacement relations analysis showed a crucial impact of cracking length on element performance. The formation of the local slip of the interface was related to the propagation of bending and shear cracks. The crack reaching the support zone should be considered the moment of debonding of the composite element. Based on numerical and analytical studies, it can be concluded that the adopted friction coefficient correctly represents the behaviour of the interface. The presented numerical analyses will be extended and correlated with the following parameters: cohesion, friction, the soft-hard function of the interface and the strand bond slip.
