  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. Evaluation of Splitting Capacity of Bottom Rails in Partially Anchored Timber Frame Shear Walls

    Författare :Giuseppe Caprolu; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The horizontal stabilization of timber frame buildings is oftenprovided by shear walls. Plastic design methods can be used todetermine the load-carrying capacity of fully and partially anchoredshear walls. In order to use these methods, a ductile behaviour of thesheathing-to-framing joint must be ensured. LÄS MER

  4. 4. On the influence of glia on neurite outgrowth from dopamine neurons in the nigrostriatal system

    Författare :Malin Saga Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Dopamine; glia; astrocytes; olfactory ensheathing cells; development; ni-grostriatal; mesencephalon; Parkinson s disease; 6-hydroxydopamine;

    Sammanfattning : Interactions between glial cells and neurons are important during fetal develop-ment, in the maintenance of the normal functions in tile central nervous system (CNS), arid in response to injuries or diseases. Some of die motor disturbances in Parkinson's disease, a neurodegenerative disorder where one of the hallmarks is de-generation of dopamine (DA) neurons and concomitant depletion of DA in stria-tum, can be alleviated by intrastriatal grafting of embryonic DA tissue.

  5. 5. Structural Analysis of Deep Composite Box-Type Components with application to a proprietary stabilising timber wall element

    Författare :Seyed Rasoul Atashipour; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The stabilising wall element of the Trä8-system is a deep box-type beam/column element which is made of different types of timber composites including framing members of gluedlaminated timber (glulam) and sheathings of laminated veneer lumber (LVL). This element is used as a ―shear wall‖ in multi-storey buildings up to four storeys. LÄS MER
