Abstract
This paper proposes an alternative method of calculation based on the Least Squares method to determine the longitudinal modulus of elasticity in timber beams with structural sizes. The developed equations require knowledge of three points measured in displacements along the element, allowing greater reliability on the response-variable, using the static bending test in three and in four points. The proposed methodologies were employed together, aiming to verify possible differences between the values of the modulus of elasticity. The results for <i>Eucalyptus grandis</i> timber showed statistical equivalence between the methods. Thus, the modulus of elasticity can be obtained by both schemes of structural tests applied.
