Application & Function
→Widely used in bending strength and apparent modulus of elasticity, tension strength parallel to grain, tension strength perpendicular to grain, compression strength parallel to grain, compression strength and modulus of elasticity perpendicular to grain, beam shear strength, bearing strength perpendicular to grain, bearing strength parallel to grain test for structural timber.
→Test standards: AS/NZS4063.1 Characterization of Structural Timber Part 1: Test Methods
→It specifies test methods for measuring the structural properties of rectangular sections sawn solid timber of commercial structural size.
→Bending strength and apparent modulus of elasticity: is determined from a simply supproted four point beam test configuration.
→Tension strength parallel to grain: The length of a test piece between grips shall be equal to or greater than (8d+2000)mm. An axial tension load shall be applied to a test piece at a uniform rate of loading until failure occurs.
→Tension strength perpendicular to grain: it is determined from a three point bending test configuration.
→Compression strength parallel to grain: The length of a test piece shall not be less than (8d+2000)mm. An axial compression load shall be applied to a test piece at a uniform rate of loading until failure occurs.
→Compression strength and modulus of elasticity perpendicular to grain:
→Beam shear strength: it is determined using a three point bending test configuration.
→Bearing strength perpendicular to grain:
