  1. 1. Steel-to-timber dowel joints : Influence of moisture induced stresses

    Författare :Johan Sjödin; Hans Petersson; Carl-Johan Johansson; Per-Johan Gustavsson; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; moisture-induced deformations; timber structures; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

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

  3. 2. Perpendicular to grain fracture analysis of wooden structural elements - Models and applications

    Författare :Henrik Danielsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture mechanics; cohesive zone modeling; Weibull theory; wood; glulam; orthotropy; heterogeneity; hole; dowel; asymmetric loading;

    Sammanfattning : This thesis concerns experimental and theoretical work regarding perpendicular to grain fracture in wooden structural elements. The experimental part concerns strength tests of glulam beams with a hole. LÄS MER

  4. 3. Concrete pavements’ repair techniques and numerical assessment of dowel bar load transfer efficiency

    Författare :Saima Yaqoob; Johan Silfwerbrand; Larissa Strömberg; Anne Beeldens; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete pavements; Rapid repair; Precast slabs; Dowel bar; Load transfer efficiency; Betongbyggnad; Concrete Structures;

    Sammanfattning : Concrete pavements are a suitable alternative for high-traffic volume roads, concentrated loads and roads exposed to severe weather conditions. In Sweden, among other reasons, the scarcity of concrete pavements is attributed to the need for more national knowledge and expertise in the field. LÄS MER

  5. 4. The shear plate dowel joint : Research on a novel connection for heavy timber structures

    Författare :Gustaf Larsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber connection; rubber foil; resilient bond line; single dowel; heavy timber structures;

    Sammanfattning : An increased use of wood can reduce the environmental footprint of the building sector. In order to improve the competitiveness of heavy timber structures, the thesis presents a novel type of timber connection with a high degree of prefabrication. LÄS MER

  7. 5. Investigations on the Serviceability Limit State of Dowel-Type Timber Connections

    Författare :Michael Dorn; de Borst Karin; Vienna University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber engineering; dowel-type connection; experiments; simualations; Servieability Limit State; contact behavior; Byggteknik; Civil engineering;

    Sammanfattning : Dowel-type steel-to-timber connections are commonly used to transfer a large range of loads. Although they are simple to produce and assemble, the load-carrying behavior and the local stress and strain distribution within the connection area are highly complex. LÄS MER
