摘要
In the present study, bending properties (modulus of rupture (MOR). modulus of elasticity (MOE). bending work (W). and Janka plastic modulus (Z)) were investigated for 10-ply laminated lumber composed of several softwood species Sugi (Cryptomeria japonica D Don) laminae were used for the inner 8 layers, and hinoki (Chamaecyparis obtusa Sieb et Zucc) or karamatu (Lam Kaempferi Carriere) laminae were used for the outermost 2 layers In addition, laminated lumber members composed of 10 sugi laminae were also produced In order to obtain the same MOE in all laminated lumber members. laminae were graded and then arranged for manufacturing the laminated lumber Although the MOE showed almost the same value in all laminated lumber members, significant differences in MOR. W, and Z were recognized among the types of laminated lumber In all types of laminated lumber. W and Z were mainly effected by deflection at the plastic region In addition, W and Z were effected by the bending property of species forming the inner layers as well as that of the species forming the outermost layers
