Resumen:
The present
paper reports the results of an investigation regarding the relationship
between the global and the local Modulus of Elasticity in sawn timber of
Argentinean Eucalyptus grandis. For this purpose an empirical research project
with 50 beams in structural sizes subjected to bending was carried out. The
results obtained according to European standards show the values of both types
of Modulus of Elasticity and the influence of the more important strength and
stiffness reducing growth characteristics on their variation, as well as give
evidence of the effectiveness of the criterion established in the American
standard ASTM D 198 (1999) for correcting the influence of shear on the global
Modulus of Elasticity.
