  1. 1. Shear walls for multi-storey timber buildings

    Författare :Johan Vessby; Hilmer Riberholt; Växjö universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey structures; timber engineering; wind stabilization; shear walls; cross-laminated timber wall panels; fasteners; connections; sheathing; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

    Sammanfattning : Wind loads acting on wooden building structures need to be dealt with adequately in order to ensure that neither the serviceability limit state nor the ultimate limit state is exceeded. For the structural designer of tall buildings, avoiding the possibly serious consequences of heavy wind loading while taking account at the same time of the effects of gravitation can be a real challenge.

  2. 2. Analysis of shear wallsfor multi-storey timber buildings

    Författare :Johan Vessby; Bo Källsner; Anders Olsson; Ulf Arne Girhammar; Roberto Crocetti; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey structures; timber engineering; wind stabilization; shear walls; cross-laminated timber wall panels; fasteners; sheathing-to-framing connections; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

    Sammanfattning : This doctoral thesis addresses questions of how wind loads acting on multistoreytimber buildings can be dealt with by structural design of such buildings.The conventional use of sheathing either nailed or screwed to a timberframework is considered, together with other stabilizing structures such ascross-laminated timber panels.

  3. 3. Multi-fastener single-lap joints in composite structures

    Författare :Johan Ekh; Dan Zenkert; Michael McCarthy; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis deals with composite joints. Designing such joints is more difficult than metallic joints due to the mechanical properties of composite materials. Composites are anisotropic and have a limited ability of yielding. LÄS MER

  4. 4. Steel-to-timber dowel joints : Influence of moisture induced stresses

    Författare :Johan Sjödin; Hans Petersson; Carl-Johan Johansson; Per-Johan Gustavsson; Växjö universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; moisture-induced deformations; timber structures; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

    Sammanfattning : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of a loaded building depends strongly on the structural configuration and the capacity of the joints. LÄS MER

  5. 5. Biological growth on mineral façades

    Författare :Sanne Johansson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture transport; mortar; mosses; biodeterioration; lichens; moulds; mineral facades; building physics; thin rendering on thermal insulation; heat transfer; biological growth; algae; heat capacity;

    Sammanfattning : During the last years there has been reported considerable and rapid contamination on newly built rendered façades in Sweden due to biological growth. The problem is believed to occur mostly on façades of render applied on thermal insulation, but apart from this it is difficult to find clear relationships indication which façades might be infected.
