“…Currently, no standard method is available to evaluate the durability of FRP–wood interfaces9. To improve the stiffness performance of a bridge deck, Brody et al 10 reported a composite structure of laminated FRP reinforced beams (tension side) combined with concrete on the compression side with lag screws used as shear studs, effectively combining three materials. They noted that by reinforcing the top and bottom of a laminated beam, shear deflections and shear failure modes become a major factor in design.…”

Laminated timber frames behave well under dynamic earthquake loads, but the beam-tocolumn connections may be susceptible to a brittle-type failure, due to tensile stresses across wood fibres. Fibre-based materials such as nonwoven glass-fibre fabric are effective in mitigating the tensile failures and increasing the ductility of the connections. While global performance of such connections and frames shows satisfactory results, some fundamental questions associated with the performance of the composite-wood system and interface in aggressive environments, under elevated temperatures and long-term loading, must be answered before the composite systems can be safely used in engineering practice.

a b s t r a c tAs compared to other structural applications of polymeric composites, limited information is available on structural behavior of wood members strengthened with polymer composites. The focus of this paper is to evaluate the structural performance and practical use of wooden beams repaired and retrofitted with fiber-reinforced-polymeric (FRP) composites. The paper presents a summary results of an experimental study on the behavior of both Douglas Fir and Glulam wood beams repaired and retrofitted with different composite strengthening systems. In addition, the paper presents a simplified design procedure to predict the capacity of timber beams strengthened with FRP composites. Two types of composites; wet layup laminates and sandwich panels, and two lamination schedules; unidirectional and bidirectional, and two lamination geometries; U-laminate and flat laminates were evaluated. For "flexure/shear" wood beams repaired and retrofitted with bidirectional, carbon/epoxy U-shaped wet layup laminates, a total of eight Douglas Fir (Dug Fir) Larch # 1 wood beams were tested to failure. For "flexure-only" wood beams retrofitted with flat unidirectional laminates, both wet layup and precured sandwich honeycomb composites were evaluated. Experimental results indicated that the use of composites as external repair and rehabilitation elements resulted in an appreciable increase of both strength and stiffness. A practical case study is also presented that provides a step-by-step procedure for analyzing and designing a polymeric composite system for repair of partially damaged wood girders by fire.
