The main factor for strength performance of corner construction is resistance to diagonal compression and diagonal tension forces acting on joints. The strength at these points varies according to the type of joint and adhesive used. The present study examined the effects of diagonal compression and tension forces upon spline joints. Joints were constructed using three types of wood-based board and either polyvinyl acetate or desmodur-vtka adhesives. Joint strength was determined experimentally by diagonal compression and tension test methods. The results showed that the diagonal compression and tension strengths were lower in all spline-jointed wooden board structures which used polyvinyl-acetate glue and were higher in those structures which used desmodur-vtka glue.


Key word: Glue, wooden joint, strength of diagonal compression, strength of diagonal tensile.
