    Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


    Special setting values based on tensile properties of Norway spruce are established for four different strength grading machines. The machines included are Computermatic, Cook-Bolinder, Ersson and Dynagrade.The study shows that the yield of timber to be used in tension, such as laminations for glulam, may be increased by basing the setting values on test results of the tensile properties rather than using the strength classes definen in EN338.
