  1. 6. Stress-laminated-timber bridge decks subjected to ultimate loads

    Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultimate-load tests; Stress-laminated timber; Timber bridges;

    Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. LÄS MER

  3. 7. Probabilistic System Effects in Timber Structures

    Författare :Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 9. 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

  7. 10. 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
