Characteristic bending strength of beech glulam

Abstract: This project was carried out to derive the characteristic bending strength of beech glulam. 47 full size glulam beams with combined symmetrical lay-up were produced. For this purpose mechanical grading was used to classify the lamellae according to the dynamic MOE. The beams were tested according to EN 408. The bending strength exceeds 44,5 N/mm². The structural properties of beech boards were determined as input for a finite-element-based computer model. It was specifically developed to predict the bending st… Show more

“…Slope of grain is generally difficult to determine on beech timber and thus was disregarded as grading criteria which is in line with the requirements according to DIN 4074-5 (DIN 2008). The effective quality of the untreated timber-in particular regarding the absence of significant knots-implies a much greater potential for these wood samples than strength class D40 which is in line with studies on the strength of glulam beams made of beech (Frese and Blass 2007).…”

“…In general, one can assert that wood species characterized by a more regular structure of annual rings, such as birch, is more appropriate for the given purpose of application. Frese and Blaß (2006) found similar results in their work. Based on the results depicted in Fig.…”
