  1. 1. Embedment Behavior of Steel Dowel in Timber: Influence of Moisture Content, Assembly History, and Artificial Cracks : An experimental and numerical study of embedment strength and stiffness of steel dowel in timber with different wood moisture content and assembly history

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Zijad Shehadeh; [2022]
    Nyckelord :Embedment strength; Embedment stiffness; Moisture content; Assembly history; Artificial cracks; Steel Dowel;

    Sammanfattning : Timber is becoming an increasingly popular construction material particularly due to its great environmental properties. Just alone around Linnaeus University in Växjö city, dozens of multistory buildings in timber have risen. LÄS MER

  3. 2. Wood and moisture-induced strains in a large deformation setting in 3D

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Fredrik Ström; Anwar Obeido; [2022]
    Nyckelord :Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Sammanfattning : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. LÄS MER

  4. 3. Modeling of moisture-induced deformations and stresses in cross-laminated timber and timber-concrete composite floors

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Marcus Johansson; [2021]

    Sammanfattning : Korslimmat trä är ett tämligen nytt material, bestående av korslagda lager av brädor. Produkten tillåter nya byggmetoder och kan ses som ett grönare alternativ till stål och betong. Dess uppbyggnad gör det mer robust och mindre beroende av träets varierande egenskaper för olika geometriska dimensioner. LÄS MER
