Abstract: Four large glulam beams with notches on the tension side were tested for strength and stiffness. Using either bending net section beam theory or shear formula to calculate crack propagation critical load is very unconservative. ...

Abstract: The mixed mode fracture failure of eastern red spruce (Picea rubens) was investigated by means of single edge notch and center crack specimens with various crack inclinations in the tangential‐longitudinal plane with ...

Abstract: Current procedures used to sort round timber beams into structural grades rely on visual grading methods and property assignments based on modification of clear wood properties. This study provides the technical basis for ...
