Influence of the number of lamellas upon the mechanical properties of poplar beams.

This work presents the influence of the lamellas number on the bending strength and the deflection of poplar beams. The behaviour of beams while keeping the same section, but varying the number of lamellas between 2 and 5 was studied. For each structure, ten specimens were tested until rupture occurred, so as to create a real reference base. The results can be applied in the design of wood constructions
