Beams from the Glued Laminated Timber Experiment versus FEM Model
Result description
Twenty beams from the glued laminated timber were subjected to the bending tests. Displacements and some local modulus of elasticity were measured during loading. Local modulus of elasticity in the fibers direction was tested in the 1448 places independently on the loading. Results both tests of local E are the same. Precisely according to experiments are made FEM models. The agreement between experiment and calculation is excellent. Values of local modulus of elasticity were statistic evaluated in lamellas. Three new beams were determined only on the base statistic inputs. First beam had extremely small E (on the level 0,05 cumulative probabilistic function) in the top and down lamellas. Second beam had in top and down lamellas average E. Third beam had in top and down lamellas high value of E (on the level 0,95 cumulative probabilistic function). Range of the displacements of these three beams was the same as in experiments.
