Probabilistic Models for the Tensile Properties of Split Boards and Their Application for the Prediction of Bending Properties of Engineered Timber Products Made of Norway Spruce

The main strength and elastic properties of structural timber products, such as glued laminated (glulam; GLT) cross-laminated (CLT), are usually described via load-bearing models, which use the tensile parallel to grain base material boards finger joints input parameters. These models assume that strength-graded will retain their full dimensions in final product. In some applications or cases, however, products split lengthwise, e.g., split/resawn glulam, comprise a random share width randomly lengthwise lamellas. As result splitting, assigned these during grading process cross-sections no longer valid. Examples novel flex_GLT-beams cut out from large dimensional multi-laminated panels. following paper, bending system effects resawn glulam by means 3D stochastic-numerical beam model uses probabilistic create values for unsplit well joints. successfully validated our own tests literature applied numerous parameter studies.
