EXPERIMENTAL INVESTIGATION OF BENDING BEHAVIOR OF HYBRID TIMBER BEAMS REINFORCED USING STEEL BARS SUBJECTED TO CYCLE LOADING

Based on the experiment of timber rectangle beams made of pine and fir reinforced with CFRP/AFRP hybrid FRP (HFRP) sheets. The failure modes and bending bearing capacity and load-deflection curves and strain distribution at mid-span section were analyzed. The results showed that: Comparing with the specimens without being reinforced by HFRP, there is certain improvement in bending bearing capacity and stiffness of the specimens reinforced with HFRP respectively. Bending bearing capacity of the pine specimens improve 18.1%~62.0% and bending bearing capacity of the fir specimens improve 7.7%~29.7%. Stiffness of the pine specimens improve 13%~21%, and stiffness of the fir specimens improve 6%~10%. Based on the experimental data, the computing formulas of bending bearing capacity of timber rectangle beams made of pine and fir reinforced with HFRP were presented.

Externally Prestressing

The external post-tensioning technique has been commonly used in the construction field because it facilitates the analysis of structures and is widely applicable for many types of structures. In this research, 12 steel H-beams were built and tested in terms of the amount of tendon or prestressing force. The results show that the externally prestressing method can increase ultimate bearing capacity of the beams. The prestressing force is the significant factor that influence the strengthening of steel H-beams. However, the amount of deviators cannot significantly influence the bearing capacity.
