Transformed-section method applied to multispecies glulam timber beams subjected to pure bending

Abstract

An analytical model, based on the Parallel axis theorem (Steiner theorem) and the procedure of the transformed-section method applied for the evaluation of the elastic moduli of composite timber beams, with different tensile-compressive elastic behavior, is proposed. A comparison between experimental and analytic results has been made on multispecies glulam beams (Pine and Platanus timber), compared with mono-species ones. As well, the work presents the results of a parametric analysis, based on the global modulus and the equivalent moduli in tension and compression.
