Abstract: The general solution to the plane stress problem for a cylindrically orthotropic beam is used, with a point-matching technique, to analyze the radial stresses in pitched and tapered, glued-laminated timber beams. Maximum values for these radial stresses are given for several geometrical configurations. The currently used design method is found to underestimate the stresses when the beam has variable depth.
