  1. 26. Creep aspects of softwood from the cell-wall level to structures

    Författare :Rhodel Bengtsson; E. Kristofer Gamstedt; Mahmoud Mousavi; Reza Afshar; Falk Wittel; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Creep; Solid Mechanics; Wooden Materials; Linear Viscoelasticity; Experiments; Materialvetenskap; Materials Science;

    Sammanfattning : This thesis addresses the intricate mechanical behaviour of natural materials, with a particular focus on wood. Despite millennia of use, understanding the mechanical behaviour of wood materials remains challenging due to their complex microstructures. LÄS MER

  4. 28. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    Författare :Hassan Mehri; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Sammanfattning : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.
