| The paper describes the investigations of concrete composite units consisting of two concrete parts. In each test series the interface was differently arranged and characterised by different strength parameters. They were: non-reinforced interface with existing adhesion, reinforced interface with existing adhesion and reinforced interface with broken adhesion. Simply-supported beams were subjected to four point bending. The failure of all beams was the result of exceeding the shear resistance of the support zones, but the cracks pattern in each series was different. The paper presents the results of the tests, in particular: deflection, stresses in the longitudinal and transverse reinforcement and strains of concrete. The distribution of strains along the height of the beam and the slip between the connected parts are also described. |
