  1. 1. Catenary action to prevent progressive collapse in multistorey timber buildings : An experimental study of tube joints

    Master-uppsats, Luleå tekniska universitet/Träteknik; Luleå tekniska universitet/Institutionen för tillämpad fysik, maskin- och materialteknik

    Författare :Sivert Knutsen; [2023]
    Nyckelord :wood; engineering; construction; massive timber; tube joints; Progressive collapse;

    Sammanfattning : In the modern building industry wood as a building material has been looked on as one of the solutions to lower the environmentally impact of the building industry. Building types that normally have been reserved for concrete and steel are today being built with wood as main load bearing component. LÄS MER

  3. 2. A measurement method for damping of drive shaft

    H-uppsats,

    Författare :Anders Bertilsson; [2019-07-03]
    Nyckelord :Samhällsbyggnadsteknik; Civil Engineering;

    Sammanfattning : Sound in our society is beginning to be a health hazard in many places. This leads to legislation and recommendations by public authorities and governments. For a truck the sound pressure level should not exceed 80 dB(A) during a drive-by test set by international standards. LÄS MER

  4. 3. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mattheüs Lucassen; [2019]
    Nyckelord :Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Sammanfattning : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. LÄS MER

  5. 4. Study of glue-laminated timber connections with high fire resistance using expanded steel tubes

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :David Ronstad; Niklas Ek; [2018]
    Nyckelord :Expanded steel tubes; Glue-laminated timber; Fire resistance; Glue-laminated timber connection; Expanderade ståltuber; Limträ; Brandmotstånd; Limträförband;

    Sammanfattning : A key factor regarding fire safety of timber buildings is the performance of connections between the structural elements, since this determines the load-carrying capacity of the structure. Traditional timber connections do generally perform poorly in a fire compared to surrounding parts since the joints often consist of exposed metal parts and cavities which locally decreases the fire resistance.

  7. 5. Ledlösning till Kiruna Wagons Helix Dumper Wagon

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Jonathan Petersson; [2016]
    Nyckelord :;

    Sammanfattning : A high degree of wear has been identified in the hinge between load cube and underframe on one of Kiruna Wagons freight cars. The wagon is mainly used in the transport of iron ore, which means that it operates in a very dusty environment. The excessive wear results in an increased service demand and high downtime of the wagon. LÄS MER
