  2. 1. Quality of Structural Timber - End-User Requirements and Performance Control

    Author : Mikael Perstorper; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The performance and quality of structural timber products cannot solely be defined by mechanical properties. It is the totality of features of a product that determines its ability to satisfy the customer. This thesis covers three aspects within the context of structural timber quality: Quality requirements for structural timber products. READ MORE

  5. 3. Modelling and strength grading of structural timber and glulam lamellae on the basis of optical scanning and dynamic excitation

    Author : Andreas Briggert; Anders Olsson; Jan Oscarsson; Mikael Perstorper; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre direction; finger joint; machine strength grading; knots; tracheid effect; Norway spruce; Byggteknik; Civil engineering;

    Abstract : Machine strength grading of sawn timber is a sawmill process in which density, modulus of elasticity (MOE) and bending or tensile strength are predicted such that the timber can be assigned to strength classes. The predictions of these properties are performed using one or several so-called indicating properties (IPs), which represent a board property, or combination of board properties, measured non-destructively.

  6. 4. Strength grading of structural timber and EWP laminations of Norway spruce : Development potentials

    Author : Jan Oscarsson; Anders Olsson; Marie Johansson; Mikael Perstorper; SP Sveriges Tekniska Forskningsinstitut; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; bending strength; fibre angle; grain angle; knots; laser scanning; machine strength grading; modulus of elasticity; strain measurement; structural timber; tensile strength; wood; böjhållfasthet; draghållfasthet; elasticitetsmodul; fibervinkel; konstruktionsvirke; kvistar; laserskanning; maskinell hållfasthetssortering; trä; töjningsmätning; Byggteknik; Civil engineering;

    Abstract : Strength grading of structural timber is a process by which value is added to sawn products. It is to the greater part carried out using machine grading based on statistical relationships between so called indicating properties and bending strength. READ MORE
