Abstract: 
The main objective of the research project reported in this paper is to develop a new type of high performance light beams or wood panels that will increase the performance of usual beams (timber steel or RC beams) by combining FRP rebars cast in a ultra-high-performance concrete with short fibre reinforcement (UHPC-SFR). The beam is obtained to get a light beam with a high compressive and tensile capacity to sustain high bending moment and to be also shear resistant. The hybrid beam thus obtained possesses a higher bending stiffness than a glulam beam and with a higher ultimate load capacity. The load-displacement and momentcurvature relationships are obtained from 30 large scales beams specimens and 5 wood panels. The results illustrate the potential interest of such composite beam configurations. The dynamic behavior is studied based on the vibration criteria. The technique used to verify vibration criteria is based on EN 1995-1-1 and Eurocode 5. The dynamic behaviour is improved allowing getting higher beams span.
