Abstract

This paper investigates the tensile strength and stiffness of low quality beech sawn timber. In addition, the influences of visual and physical characteristics of the beech boards on the mechanical performance were analysed. Visual characteristics like knots, pith or fibre deviation as well as density and dynamic modulus of elasticity were examined regarding their influence on the tensile strength and stiffness of the beech boards. The subsequent destructive testing was performed according to EN 408on 214 beech boards with two different cross sections. Correlation analyses regarding non-destructive and destructive parameters indicate possibilities and limits of strength grading in terms of beech sawn timber. This paper complements many investigations of the last years focusing mainly on the mechanical behaviour of middle and high quality beech sawn timber and glulam. As a large proportion of beech sawn timber is low quality material, a better understanding of its behaviour may lead to higher yield in combination with economic benefits as well as to more reliable strength grading and more efficient material use.

OtherWCTE is the world's premier forum for presenting and discussing the latest technical and architectural developments and innovations in wood or timber construction. WCTE is the most prestigious international event in timber engineering, engineered wood products and design of timber structures, which is held biennially in different parts of the world and attracts researchers, engineers and architects, code consultants and building officials, contractors and project managers, fabricators and suppliers from all continents. During WCTE 2018 the traditional focus on timber engineering and material science will be complemented by architecture related topics such as evaluation methods for green buildings and by an own platform for computer-based methods for modelling, parametric design, production, etc.
