    Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER

  5. 4. Stabilising system for multi-storey beam and post timber buildings

    Författare :Gabriela Tlustochowicz; André J.M. Jorissen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : For multi-storey timber buildings, the stabilisation against horizontal loads is one of the key issues, which becomes more severe with height. There are a few main concepts utilised to resist lateral forces; shear wall action, diagonal bracing, and frame action. LÄS MER

  7. 5. Testing and analysis of composites with 3D woven reinforcement

    Författare :Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []

    Sammanfattning : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. LÄS MER
