Abstract: The four tested beams were frame worked with steel rebars or mixed CFRP-steel armatures according to Eurocode. The first beam that combines high performance concrete without short-fibers and steel framework permits to verify the design and to identify the bending behavior. The mechanical test done on the second beam in HPFRC permits to measure the contribution of the short-fibers in the tensile and the shear zone parts of the beam. In this case, no transverse framework is used following the design. For the two last beams, the objective is to confirm the possibility to use some Carbon Fiber Reinforced Polymer framework mixed with usual steel framework in order to keep ductility in the structure. The paper discusses the results obtained and compares the efficiency of such composite beams with usual RC beam.
