The present study examined the bending moment capacity and rigidity of T-type out-of-plane furniture joints and investigated the effects of heat treatment, wood species, and joint type factors on these joints. Heat treatment method clearly decreased the modulus of rupture (MOR) and the modulus of elasticity (MOE) of selected wood species. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2014) 38: 148-158 © TÜBİTAK doi: Research Article Mechanical properties of heat-treated wooden material utilized in the construction of outdoor sitting furniture 1, 1 2 Nurgül TANKUT *, Ali Naci TANKUT , Mustafa ZOR Department of Forest Industrial Engineering, Faculty of Forestry, Bartın University, Bartın, Turkey 2 Furniture and Decoration Program, Çaycuma Vocational School, Bülent Ecevit University, Zonguldak, Turkey 1 Received: Accepted: Published Online: Printed: Abstract: The present study examined the bending moment capacity and rigidity of T-type out-of-plane furniture joints and investigated the effects of heat treatment, wood species, and joint type factors on these joints. Heat treatment method clearly decreased the modulus of rupture (MOR) and the modulus of elasticity (MOE) of selected wood species. The bending strength of wood samples was reduced after the heat treatment, decreasing with increased loss of mass. For the heat-treated T-type joints, maximum bending strength values were obtained with Iroko (Chlorophora excelsa) for both mortise and tenon (MT) joints and blind MT (BMT) joints. The lowest reduction in bending strength was observed in Ash (Fraxinus excelsior L.) constructed with MT joints and with BMT joints. In general, the BMT joint had higher bending strength than MT joints. The best rigidity constant () was obtained with control Iroko BMT joints, while the worst rigidity constant () was obtained with control Oriental spruce (Picea orientalis L.) MT joints. In terms of heat-treated samples, the best rigidity constant () was obtained with Black pine (Pinus nigra L.) MT joints, while the worst rigidity constant () was obtained with Oriental spruce BMT joints. The maximum performance in joint stiffness was determined for Iroko sample BMT joints and
