Identification of weak sections in gulam beams using calculated stiffness profiles based on lamination surface scanning
(2014) WCTE 2014, World Conference on Timber Engineering- Abstract
- <p>Modelsfor estimation of structural properties of glued laminated timber (glulam) aregenerally based on the relationship between properties of the individuallaminations and the properties of the glulam. In this investigation, a recentlypresented machine strength grading method based on laser scanning of fibredirection fields was applied for determination of axial modulus of elasticity(MOE) profiles along glulam laminations. These profiles were then used tocalculate edgewise bending MOE (<em>E</em><sub>B</sub>)profiles of glulam beams. The objectives were to investigate the relationshipbetween position of bending failure and position of lowest <em>E</em><sub>B</sub> value along... (More)

The objectives were to investigate the relationshipbetween position of bending failure and position of lowest <em>E</em><sub>B</sub> value along investigated beams, and the relationshipbetween the mentioned <em>E</em><sub>B</sub>value and bending strength of the beams. It was found that both relationshipswere rather weak, whereas local bending MOE determined in accordance with EN408 was predicted with high accuracy on the basis of <em>E</em><sub>B</sub> profiles.</p> (Less)
