  1. 41. High capacity timber joints : Proposal of the shear plate dowel joint

    Författare :Gustaf Larsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An increased use of wood can reduce the environmental footprint of the building sector by being a renewable and ecological material. In order to improve the competitiveness of heavy timber structures, this thesis presents a novel type of timber connection with a high degree of prefabrication, which utilizes a resilient bond line.

  3. 42. Finger-Joints for Laminated Beams : Experimental and Numerical Studies of Mechanical Behaviour

    Författare :Erik Serrano; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Finger-joints; Laminated timber; Testing; Nonlinear fracture mechanics; Finite Elemente Method; Lamininating effect;

    Sammanfattning : The introduction of laminated timber, glulam being an example, allowed many of the disadvantages associated with solid wood to be overcome. The disadvantages in question are mainly those related to the size and shape limits of structural elements made of solid wood and to the large variability in such material properties of solid wood as strength and stiffness.

  4. 43. Hemicellulose-based wood adhesives

    Författare :Tijana Todorovic; Eva Malmström; Linda Fogelström; Francisco Vilaplana; Magdalena Sterley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The increasing sustainability concern encourages the society to use sustainable resources. In the wood industry the main component is from a renewable resource, but others are not. One of the fossil-based components is the adhesive. LÄS MER

  5. 44. Determination of Weibull Parameters by Single Fibre Fragmentation for use in Modelling of Paper Tensile Properties

    Författare :Carl-Henrik Ljungqvist; []
    Nyckelord :;

    Sammanfattning : The thesis presents a method for characterization of pulp fibre tensile strength. Single Fibre Fragmentation (SFF) and Weibull statistics were used. Methods for specimen preparation, sampling and analysis of fragmentation data from digital images were developed. LÄS MER

  7. 45. Shrinkage cracking of steel fibre reinforced self compacting concrete overlays: test methods and theoretical modelling : test methods and theoretical modelling

    Författare :Jonas Carlswärd; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Steel fibres are often applied as crack reinforcement in overlays even though methods for the design with respect to crack widths are not yet available. Thus, the intention was for the research to form a basis for future design of overlays with respect to cracks. A main ambition was to give guidance on e.g. LÄS MER
