Veneer-reinforced timber – Numerical and experimental studies on a novel hybrid timber product
https://orcid.org/0000-0003-0613-1688
Highlights Introduction of new type of wood building material based on glulam from spruce and veneers from beech. Inherently reinforced wood product with high capacity for load redistribution. Proof of significantly improved properties perpendicular to the grain and in shear. Multiplied load-carrying capacities at details such as notches, holes and cross-connections. Homogenization of multiple glued veneer layers leads to mean tensile strengths > 100 MPa.
Abstract This paper deals with the development of a novel veneer-reinforced timber product for load-bearing applications – veneer-reinforced timber. For this composite timber product, veneers are inserted vertically into a glulam cross-section to act as reinforcement for shear and tension stresses perpendicular to the grain. By arranging the veneer layers between the glulam components at angles of 0°, 45° and 90°, the highly anisotropic strength and stiffness properties of glulam are homogenized. By means of numerical simulations and experimental investigations, the load-bearing behavior and the efficiency of veneer-reinforced timber are investigated. The results substantiate a considerable increase in load bearing capacities of veneer-reinforced timber with notches, holes or cross connections. Studies and derived recommendations on the effect of the inclination of the veneer on the shrinkage behavior of this composite timber product conclude this paper.
