<br/><br/> <br/><br/>ABSTRACT<br/><br/>The objectives of this study were to evaluate the relationship between the density and the EW<br/>(modulus of elasticity) values obtained by two non-destructive methods: the accuracy of an<br/>expeditious method using a graduated ruler; and the homogenization of elasticity between the<br/>methods for glulam elements. In the analysis, displacements were measured with a graduated<br/>ruler and an automatic data acquisition system of 136 glulam pieces with corresponding structural<br/>size was used. The methods were evaluated by correlations, and the homogenization of elasticity<br/>was evaluated by the Tukey test. We found that density does not influence the EW values obtained<br/>by the studied methods, and it is concluded that an expeditious method using a graduated ruler<br/>can be used to determine EW by applying a corrected equation.<br/><br/>Keywords: planted forest timber, paricá, modulus of elasticity, glulam.
