Abstract: This investigation focuses on Ultra-High Performance Fibre Reinforced (UHP-FRC) concrete as a possible material for ice shield for offshore applications. A composite flexural element was constructed from two layers of concrete. The top layer was made with UHP-FRC with a compressive strength of 170 MPa and thickness 50 mm. The bottom layer is a High Performance Concrete (HPC) with a compressive strength of 85 MPa and thickness of 180 mm. The two layers were connected with shear keys and T-headed studs to transfer the interface shear between the layers. The experimental program investigated the structural behaviour of the composite specimen. The results revealed that there was an increase in the ultimate flexural capacity when compared to the non-composite beams. The T-headed studs were capable of transferring the interface shear up to the failure of the composite specimen. On the other hand, the use of shear keys did not enable the full transfer of the shear stresses in the plastic region. The equation proposed by Loov and Patnaik (8) gave the best predictions of the interface shear stress when compared the experimental results.
