摘要: The final objectives of this study are the proposal of the new shear failure test method used bending method and the estimation of pure shear strength of Japanese cedar. Since Japanese cedar has very low bending strength than any kind of timber, therefore that shear failure occur rarely in advance of bending failure by using bending method. Thus, when shear failure tests of Japanese cedar are conducted by using bending method, it is necessary to stiffen and to reinforce with any materials which have Young's modulus and high bending strength such as steel plate. However, if steel plates were bonded to timber with epoxy resin such as steel-plates-inserted glulam-beams, shear stress concentrations occur at the interface between steel plates and timber, and the specimen fractured at there. In this case, the obtained values can be far lower than pure shear strength. Thus, in this study, by using FEA we tried to design the specimen without stress concentrations at the interface and the shear failure occur ahead of bending failure. In addition, the specimens designed by FEA were actually made, and measured the shear strength.
