  2. 1. Benefits of strengthening timber with fibre-reinforced polymers

    Author : Alann André; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental results; Carbon; Timber; Tension perpendicular to the grain; Ductility; Flax; Reinforcement; Compression failure parallel to the grain; Kinkband; Composite materials; Numerical model; Analytical model; FRP;

    Abstract : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. READ MORE

  4. 2. Development of prefabricated timber-concrete composite floors

    Author : Elzbieta Lukaszewska; Hans-Joachim Blass; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Timber-concrete composite structures were originally developed for bridges and upgrading of existing timber floors, but finds today new applications in multi-storey buildings. Most of the research performed to date has been focused on systems where "wet" concrete is cast on top of timber beams with mounted connectors. READ MORE

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

    Author : Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; Vienna University of Technology; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Development and Evaluation of Mechanical Joints for Composite Floor Elements with Cross Laminated Timber

    Author : Nicolas Jacquier; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : One of the important issues in the development of a multi-storey timber construction system is the definition of the floor solution. This thesis focuses on the development of composite floor solutions where Cross Laminated Timber (CLT) panels are used as a base element. READ MORE

  7. 5. Strengthening of timber structures with flax fibres

    Author : Alann Andre; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. READ MORE
