THE INFLUENCE OF ORTHOTROPY LEVEL FOR PERPENDICULAR TO GRAIN STRESSES IN GLULAM DOUBLE TAPERED BEAMS

Abstract eng:
This paper presents parametric analysis of distribution of the delamination normal stress perpendicular to the grain in double tapered, simply supported beams made of glued laminated timber. The parameters are height of the beam in the apex area and the level of diversity of orthotropic material properties from the isotropy to orthotropy according to the standards of design. The calculations are performed by the finite element method (FEM) in terms of the linear theory of elasticity with plane stress assumption. The results of the FEM calculations are referred to the indications of the design standards.
