  2. 1. Modular long-span timber structures : a systematic framework for buildable construction

    Author : Anders Björnfot; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : One of the identified reasons for the low amount of timber construction in Sweden is a general lack of knowledge about timber engineering and how timber can be used to its full advantage. One way for increased timber construction is the development of a cost-efficient and easy to comprehend building system. READ MORE

  4. 2. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Author : Dan Engström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Abstract : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. READ MORE

  5. 3. Glulam timber arches : strength of splices and reliability- based optimisation

    Author : Nils Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Arch structures are very sensitive to changes in the distribution of the load as well as to changes in their shape. A slight change in the load distribution may imply internal forces for which the arch is not designed. READ MORE

  6. 4. In-situ assessment of timber structures - Assessment methods and case studies

    Author : Thomas Lechner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-destructive testing NDT ; historical structures; density; In-situ assessment; timber structures; mechanical properties; assessment methods; X-ray;

    Abstract : In the assessment of timber structures, diagnostic investigations with reference to the condition and structural performance of these structures are necessary and often require appropriate health monitoring techniques. This thesis covers four aspects within the research area of the in-situ assessment of timber structures based on scientific knowledge and guidelines to perform assessment of existing timber structures:IDetermination of density of wood with portable X-rayThe mechanical performance of timber is often strongly related to the density of wood.

  7. 5. Strengthening of timber structures with flax fibres

    Author : Alann Andre; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. READ MORE
