  1. 11. Benefits of strengthening timber with fibre-reinforced polymers

    Författare :Alann André; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental results; Carbon; Timber; Tension perpendicular to the grain; Ductility; Flax; Reinforcement; Compression failure parallel to the grain; Kinkband; Composite materials; Numerical model; Analytical model; FRP;

    Sammanfattning : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. LÄS MER

  3. 12. Moisture-related properties of modified timber - an experimental study

    Författare :Hannah Epmeier; Chalmers tekniska högskola; []
    Nyckelord :Scots pine; material properties; chemical modification; building components; timber; bending creep;

    Sammanfattning : Wood has long traditions as a structural and building material. In those cases in which its natural features are not sufficient, chemical modification can eliminate some shortcomings. LÄS MER

  4. 13. Moisture Induced Stress Perpendicular to Grain in Timber Structures

    Författare :Martin Häglund; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood.; timber; perpendicular to grain; load combination factor; tensile stress; mechano-sorption; Moisture induced eigen-stress; varying moisture content;

    Sammanfattning : Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. LÄS MER

  5. 14. Performance of Stress-Laminated-Timber Bridge Decks

    Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; butt joints; non-linear modelling; stress-laminated timber; linear modelling; prestressing; timber bridges; interlaminar slip; FE modelling; laboratory tests; durability;

    Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from a number of timber or glulam beams positioned side by side and stressed together using high-strength steel bars. LÄS MER

  7. 15. Modular long-span timber structures : a systematic framework for buildable construction

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

    Sammanfattning : 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. LÄS MER
