Abstract
This paper deals with the determination of the modulus of elasticity of boards, finger joints
in tension and hence builds up glued laminated timber (GLT). Emphasize has been taken on
determination of G-modulus of GLT by execution of both standardized test methods acc. EN
408, by torsion tests and application of shear-fields in constant transverse force areas during
destructive four-point bending tests acc. EN 408. Comprehensive evaluations of
relationships between G- and E-module and related mechanical properties have been carried
out. Furthermore product of (E · G) has been examined as relevant value for lateral torsional
buckling based on test results and simulations. A proposal for further standardization for
determination of G-modulus of GLT acc. EN 408 will be presented. Simulations evaluate the
influence of selected parameters on expectable G-modulus. The data states as bases for
further regulations concerning lateral torsional buckling of GLT in dependence of size in
comparison to solid wood beams and should be considered for standardization
