    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

  3. 2. 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

  4. 3. Nonlinear modeling of reinforced dowel joints in timber structures : a combined experimental-numerical study

    Författare :Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; Vienna University of Technology; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Steel dowels are indispensable elements for the design of joints in modern timber structures. Dowels are broadly used because of their flexibility in design and easy assembling on-site, as well as due to their advantageous mechanical behavior. LÄS MER

  5. 4. Application of cohesive modeling in joining technology : Thick adhesive layers and rivet joints

    Författare :Saeed Salimi; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology;

    Sammanfattning : This thesis summarizes the development of cohesive modeling of joints. It presents some new developments regarding the effects of non-zero thickness of adhesive layers and a novel approach of using the concept of cohesive modeling to characterize the failure behavior of rivet joints.

  7. 5. Rock mass behavior under hydropower embankment dams : results from numerical analyses

    Författare :Alexander Bondarchuk; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Bridges are an important element of the infrastructure today. The technical competence has reached high levels in most countries and the limits given to a bridge designer are set by economic restrictions rather than technical skill. LÄS MER
