TI  - Mechanical properties of heat-treated wooden material utilized in the construction of outdoor sitting furniture
AB  - Te present study examined the bending moment capacity and rigidity of T-type out-of-plane furniture joints and investigatedthe efects of heat treatment, wood species, and joint type factors on these joints. Heat treatment method clearly decreased the modulus ofrupture (MOR) and the modulus of elasticity (MOE) of selected wood species. Te bending strength of wood samples was reduced aferthe heat treatment, decreasing with increased loss of mass. For the heat-treated T-type joints, maximum bending strength values wereobtained with Iroko (Chlorophora excelsa ) for both mortise and tenon (MT) joints and blind MT (BMT) joints. Te lowest reductionin bending strength was observed in Ash (Fraxinus excelsior L.) constructed with MT joints and with BMT joints. In general, the BMTjoint had higher bending strength than MT joints. Te best rigidity constant (7.21) was obtained with control Iroko BMT joints, whilethe worst rigidity constant (15.10) was obtained with control Oriental spruce (Picea orientalis L.) MT joints. In terms of heat-treatedsamples, the best rigidity constant (7.59) was obtained with Black pine (Pinus nigra L.) MT joints, while the worst rigidity constant(14.01) was obtained with Oriental spruce BMT joints. Te maximum performance in joint stifness was determined for Iroko sampleBMT joints and Iroko MT joints. Lowest reduction in joint stifness was observed in Scotch pine MT joints and Ash BMT joints. Heattreatment, wood type, and joint type had a signifcant efect on the bending strength of T-type MT post-rail joints. BMT joints producedfrom heat-treated Iroko wood can be considered as the most durable T-type joint for outdoor sitting furniture construction.
