  3. 22. Vippning av stålbalkar i hallramar

    Författare :Peter Collin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The present thesis, written in Swedish, deals with the problem of lateral-torsional buckling, especially in gable frames. The aim of the work presented is to suggest an improved design method that takes into account the translational and rotational restraint produced by the roof and wall. A particular question is the behaviour of the comer region. LÄS MER

  4. 23. Influence of structural timber variability on reliability and damage tolerance of timber beams

    Författare :Ireneusz Czmoch; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The thesis addresses two main problems: 1) Probablistic modelling of lengthwise variability in structural timber, 2) Reliability and damage tolerance analysis of beams made of structural timber. Timber is considered as an elastic-brittle material. Dependence of timber properties on time and environment conditions is neglected. LÄS MER

  7. 25. Physically Based Engineering Models for NCF Composites

    Författare :Fredrik Edgren; Dan Zenkert; Michael WIsnom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; Konstruktionsteknik;

    Sammanfattning : Non-Crimp Fabrics - NCF – are increasingly being used as reinforcements in high performance composite materials. NCF offer the manufacturing advantages from textile preforms in combination with excellent mechanical performance. This study concerns the mechanical performance of NCF composites. LÄS MER
