Abstract

Simple elastic approach is normally applied to analyse timber beam structure. This approach assumes that the beam is elastic up to failure. However, timber behaves elasto-plastic property and there is a lack of research to consider this property to predict ultimate load of the beam. Existing code of practices proposed elastic approach to predict ultimate strength of timber beam [1, 2]. In the ASTM D3737-92, the method of transformed section is proposed to predict ultimate strength and to take account the effect of inhomogeneity that present in glulam beam structure. A number of USDA researchers [3, 4, 5, 6, 7] applied a method of transformed section to predict ultimate strength of timber beam. Those researchers assumed that timber property is elastic up to failure and neglecting the actual property of timber, i.e. elasto-plastic.
