Abstract The depth adjustment factor for bending strength stated in Eurocode 5 (EC5) is only applicable to timbers having a characteristic density below 700 kg/m³ . However, most Malaysian timbers are hardwood, some with a characteristic density reaching above 700 kg/m³ . Therefore, the objective of this study was to examine whether the depth adjustment factor stipulated in EC5 is valid for Malaysian hardwood timbers. Six timber species were selected for this study, namely Kapur (Dryobalanops C.F.Gaertn.), Kempas (Koompassia Maingay ex Benth.), Keruing (Dipterocarpus C.F.Gaertn.), Light red meranti (Shorea Roxb. ex C.F.Gaertn.), Geronggang (Cratoxylum Blume) and Balau (Shorea Roxb. ex C.F.Gaertn.).… More > Graphic Abstract

Abstract The traditional tenon and mortise joint has low processing efficiency and a weak theoretical basis, making the structure easy to deform and damage, reducing the safety, and increasing waste of resources. This study aims to determine the optimum dowel center spacing parameter for chamfered-joint components and the maximum value of the strength of joints loaded into bending strength and tensile strength. In this study, an integrated optimization method combining the single-factor test and one-way ANOVA analysis was proposed to study the influence of the dowel center spacing on the bending strength and the tensile strength of chamfered-joint components made by… More >
