  1. 11. Strength and Moisture Aspects of Steel Timber Dowel Joints in Glulam Structures : An Experimental and Numerical Study

    Författare :Johan Sjödin; Erik Serrano; Per Johan Gustafsson; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; glu-lam beams; glulam structures; linear elastic fracture mechanics; moisture-induced stresses; numerical simulations; short term capacity.; Building engineering; Byggnadsteknik;

    Sammanfattning : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of e.g. a building depends strongly on the structural configuration and the capacity of its joints. LÄS MER

  2. 12. 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

  3. 13. Úhelníky s prolisem ve spojích dřevěných prvků

    Författare :Petr Sejkot; Petr Kuklík; Miloš Drdácký; Antonín Lokaj; Czech Republic Czech Technical University in Prague; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle brackets with a rib; annular ring nails; metal works for timber structures; static load tests of joints; numerical simulations of tests of joints; analytical static models of joints.; úhelníky s prolisem; kroužkové konvexní hřebíky; kování pro přípoje dřevostaveb; statické zatěžovací zkoušky přípojů; numerické simulace zkoušek přípojů; analytické statické modely přípojů.;

    Sammanfattning : The thesis deals with appropriate methods to determinate load-bearing capacities of timber structures joints using angle brackets with a rib. In these joints, annular ring nails were used as connectors.During an experimental approach, full-scale load tests of whole joints were performed. LÄS MER

  4. 14. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

    Författare :Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

    Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER

  5. 15. In-plane mechanical properties of birch plywood and its performance in adhesively bonded connections
