Title

Investigation on the effect of fiber reinforced polymer (FRP) on stress carrying capacity of miter corner joint under diagonal tension loading

Pages

  307-320

Abstract

 Fiber Reinforced Polymer (FRP) has become one of the most popular material in the reinforced, repair and rehabilitation of structure due to its ease of application and the special physical and strength characteristics. The aim of this research was to investigate the structural performance of corner joint reinforced with fiber reinforced polymer (FRP) composite under diagonal tension load. Constructed joints from two wood species; Beech (Fagus orientalis) and Fir (Abies alba), were reinforced with FRP composites including one and two layers of carbon and glass fibers and then they were tested under diagonal tension load. The miter corner joints were made using wooden pin and polyvinyl acetate adhesive. The fibers lay-up was done manually. epoxy resin was used as a polymeric matrix. Result of investigation indicated that the samples fabricated using Beech wood in comparison with Fir exhibited better results. In addition, glass fibers have shown better performance than carbon fiber as reinforcing elements. Inspection of diagonal tension specimens after failure have indicated that using FRP on the surfaces of Lshaped miter prevents joint opening. However, failure was occurred at the joint by increasing of the load and vertical displacement and wood weakness in tension perpendicular to the grain and shear parallel to the grain at dowels location due to stress concentration. The results showed that the miter corner joint made with Beech wood and two layers of glass fibers FRP had the highest stress carrying capacity.
