  1. 21. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Author : Dan Engström; Chalmers University of Technology; []
    Keywords : frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Abstract : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. READ MORE

  2. 22. Investigating Consumer Perceptions by applying the Extended Association Pattern Technique : A Study on Wooden Multistory Houses

    Author : Tobias Schauerte; Anders Baudin; Anders Pehrsson; Udo Mantau; Växjö universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Means-End Chain Theory; Means-End Theory; laddering technique; laddering; Association Pattern Technique; end use analysis; wooden multistory houses; timber construction; wood construction; wooden housing; Business and economics; Ekonomi; Forestry and Wood Technology; Skog och träteknik;

    Abstract : During the past years, the usage of wood as construction material in multistory applications has increased. In Germany and Sweden, various activities have been, and are about to be performed, to accentuate and improve the position of wooden multistory houses. READ MORE

  3. 23. Acoustic excitation and transmission of lightweight structures

    Author : Jonas Brunskog; Teknisk akustik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; point mobility; Lamb waves; wood.; Building construction; plate excitation; cavities; near-periodicity; nearly periodic; sound insulation; timber; structural acoustics; spatial Fourier transform; resilient device; prediction model; periodic; lightweight; ISO tapping machine; airborne noise; Building acoustics; impact noise; Byggnadsteknik;

    Abstract : In order to increase our knowledge of the sound transmission and radiation processes of lightweight wall and floor structures, theoretical models are needed. Detailed models may form a valuable tool. In lightweight floor structures, impact sound insulation is perhaps the most important property to consider. READ MORE

  4. 24. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

    Author : Lars Olsson; Chalmers University of Technology; []
    Keywords : laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

    Abstract : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. READ MORE

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

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

    Abstract : 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.
