Abstract
ABSTRACTThe mechanical performance of dark red meranti (Shorea spp.) containing structural finger joints was investigated in four-point bending. The influence of variation in density on the bending strength (MOR) and stiffness (MOE) of dark red meranti (DRM) was studied. The effect on these properties of variation in end pressure when bonding was examined. The orientation of finger joints and the effect of cross-sectional area of bonded joints on the bending properties were also investigated.The results of this study indicate a positive relationship between the density and the MOR of DRM specimens. Sufficiently high end pressure is needed to produce strong finger joints. The orientation of finger joints and the changes in cross-sectional area of bonded joints showed no influence on the MOR. The MOE of DRM was not affected by the finger jointing of the pieces. In conclusion, finger-jointed DRM exhibits potential for structural uses, particularly for glulam beams.
