原始语种摘要: In restructuring and restoration of timber structures, it’s necessary to evaluate the integrity of the structural elements, especially mechanical properties. For this study, two types of wood were used; a dicotyledonous - Erismasp and a conifer - AraucariaAugustifolia. This study purposes an alternative methodology for determining the modulus of elasticity (E) with non-destructive tests in reduced samples. The proposed methodology helps in the productivity and execution of tests, respecting the parameters of the Brazilian standard NBR 7190:1997. The simple flexion tests in reduced models provide compatible values with the required by the Brazilian standard, being an additional tool to evaluate new and old structures.
