Abstract: In wood-based structure design, in addition to the criteria of strengthening and stiffness, the criterion of deformability due to the creep of wood, especially in horizontal members, is a factor that often limits the availability of design. New developments have further improved structural performance, such as the strengthening of timber (glulam) beams by bonding composite material combine with an ultra-high performance fibre reinforced concrete (UHPFRC) internally reinforced with or without carbon fibre reinforced polymer (CFRP) bars. Glulam, UHPFRC and CFRP may be an interesting composite mix for responding to the problem of the creep behaviour of composite structures made of different materials with different rheological properties. This paper describes an experimental and analytical investigation on the short-term and long-term performance of hybrid beams in different environments. The results indicate beams provide an improvement in both strengthening and stiffness and can also effectively reduce the creep deflection of wooden beams.
