  1. 1. Stressed-Skin Panels of Mixed Construction - Using Wood-Based Materials, Especially Chipboard

    Författare :Robert Kliger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stressed-skin panel behaviour; wood; timber; steel; joists;

    Sammanfattning : Stressed-skin panels are structural elements widely used as floors, roofs and so on. In such panels, flanges of sheet material interact with webs of beams (joists). LÄS MER

  3. 2. Convection in Loose-fill Attic Insulation

    Författare :Paula Wahlgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; loose-fill insulation; forced convection; attics; natural convection; heat transfer; thermal insulation;

    Sammanfattning : The objective of this study is to investigate the influence of convection on the thermal performance of loose-fill attic insulation under realistic climate conditions. In order to achieve this, a large-scale attic test model has been constructed in a climate chamber. LÄS MER

  4. 3. Floor vibration : dynamic properties and subjective perception

    Författare :Fredrik Ljunggren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : This thesis covers research in the floor vibration field. Although lightweight steel framed constructions have been in focus, many results are applicable to floors in common and to some extent also to vibrations in general. LÄS MER

  5. 4. Moisture-related properties of modified timber - an experimental study

    Författare :Hannah Epmeier; Chalmers tekniska högskola; []
    Nyckelord :Scots pine; material properties; chemical modification; building components; timber; bending creep;

    Sammanfattning : Wood has long traditions as a structural and building material. In those cases in which its natural features are not sufficient, chemical modification can eliminate some shortcomings. LÄS MER

  7. 5. 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
