  1. 1. Supporting the design phase of industrialised house building using a product platform approach : A case study of a timber based post and beam building system

    Författare :Shamnath Thajudeen; Fredrik Elgh; Martin Lennartsson; Marcus Sandberg; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrialised house building; Product platform; Design support; Building system; Post and beam; Glulam; Industriellt husbyggande; Produktplattformar; Designstöd; Byggsystem; Pelar-balksystem; Limträ;

    Sammanfattning : In recent years, industrialised house building has gained shares on the Swedish house building market. The market demands for industrialised house building are exceeding the available supply of housing and experiencing a substantial increase in the housing production costs. LÄS MER

  3. 2. Strengthening of timber structures with flax fibres

    Författare :Alann Andre; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : 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. LÄS MER

  4. 3. Adhesive Joints in Timber Engineering. Modelling and Testing of Fracture Properties

    Författare :Erik Serrano; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; test method; tensile strength; stress distribution; size effect; numerical simulation; laminating effect; laminated beams; joint; glued-laminated timber; glued-in rod; fracture mechanics; finite element method; finger-joint; experiment; damage; constitutive modelling; adhesive; bending strength; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Construction technology; Anläggningsteknik; Material technology; Materiallära; materialteknik;

    Sammanfattning : This thesis, which is a compilation of seven papers, concerns the mechanical testing, numerical analysis and constitutive modelling of wood-adhesive bonds in timber engineering. Applications such as finger-joints, glued-laminated timber and glued-in rods are considered. LÄS MER

  5. 4. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction

    Författare :Jens Bergenudd; Jean-Marc Battini; Roberto Crocetti; Patricia Hamm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic analysis; Modal analysis; Pedestrian bridge; Timber; Railings; Asphalt; Slip modulus; Finite element modelling; Dynamisk analys; Modal analys; Gång- och cykelbro; Trä; Räcken; Asfalt; Förskjutningsmodul; Finita element modellering.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. LÄS MER

  7. 5. Mechanical connections using birch plywood as gusset plates in timber structures

    Författare :Yue Wang; Magnus Wålinder; Roberto Crocetti; Hans Joachim Blaß; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; mechanical fasteners; load-to-face grain angle; gusset plates; truss structures; portal frame structures; load spread angle.; Building Materials; Byggnadsmaterial;

    Sammanfattning : The use of steel gusset plates in connections for timber structures increases the environmental impact of the structure. Wood-based connections could, in this case, be ideal substitutes providing lower environmental impact as well as both better workability and mountability. Birch (Betula spp. LÄS MER
