摘要：In order to use wood in a sustainable and rational way, it is necessary to estimate its characteristics, and in the case of civil construction, the physical and mechanical properties are the most interesting. The aim of this research was to estimate the modulus of elasticity of structural pieces of Schizolobium amazonicum Herb. wood through static bending (MOEsb) and longitudinal vibration (MOElv) methods, in addition, to generate regression models to estimate the modulus of elasticity of static bending. Tests for MOEsb and MOElv estimation were carried out according to ABNT NBR 7190:1997 and FAKOPP Enterprise, respectively. Linear and quadratic regression models were used to estimate MOEsb as a function of MOElv. A multivariate regression model was also generated considering the wood density. According to the discussion of the obtained results, MOElv and MOEsb average values estimated for the studied batch of Schizolobium amazonicum Herb. wood were 9.70 and 9.07 GPa, and average density 381.21 kg/m3. Regression models proposed for estimation of MOEsb presented the coefficient of determination close to 60%.
