Abstract

To predictthe elasticity modulus of wood, an assumption is made that all of deflection is due to the bending moment. Actually the total deflection of a beam made up of a bending and shear component. The composition of the bending deflection has EI as the bending stiffness factor and for the shear deflection has a GA as the shear stiffness factor, where E is the elasticity modulus, I is the moment of inertia, G is the shear modulus and A is the cross sectional area of a beam. The shear modulus of wood can be determined by using the true elasticity modulus of full-scale specimen test and the apparent elasticity modulus of small-clear specimen test of the beam with single load at mid-point for simply supported beam. From the comparison of them the shear modulus of wood can be obtained. The resultof this research shownthat the shear modulus of Acacia mangiumis 1/17.45 multiplies by the elasticity modulus.
