  1. 1. Fallviktsförsök på skjuvarmerade betongbalkar

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Louise Atterling; My Widmark; [2022]
    Nyckelord :Concrete beams; impact load; dynamic load; shear reinforcement; shock load; vibrations; signals;

    Sammanfattning : Standards and regulations for dimensioning of load-bearing structures are based on the response of load-bearing structures subjected to loads without variation in time. In the event of an accidental load, e.g. a collision or explosion, causes the load to have a rapid variation in the time resulting in a dynamic response.

  3. 2. Beräkningsprogram för dimensionering av samverkanspelare vid rumstemperatur och förhöjd temperatur

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Abdulhak Kanatri; Naoke Felipe Rojas Hara; [2022]
    Nyckelord :;

    Sammanfattning : In recent decades, the construction industry has begun to put emphasis on making the right choice of materials and development of how technology that brings climate-safe and resource-efficient solutions. Composite construction has gained much attention in the world for its ability to utilize multiple material's advantages while compensating each other's disadvantages, for example, improved fire resistance of composite steel and concrete columns is mentioned.

  4. 3. Material Characterization and Blade Impact Simulation

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

    Författare :Gustaf Bodare; [2022]
    Nyckelord :Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Sammanfattning : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. LÄS MER

  5. 4. Brandteknisk dimensionering av limträkonstruktioner : En jämförelse mellan förenklad och analytisk dimensionering med avseende på materialåtgång

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

    Författare :Gabriel Högås; Rami Kuhail; [2021]
    Nyckelord :Design of fire protection; glued laminated timber; timber structure; analytical design; Brandteknisk dimensionering; limträ; träkonstruktion; analytisk dimensionering;

    Sammanfattning : This thesis examines the possibility of saving material by using analytical design of fire protection of glued laminated timber structures instead of the standard simplified design approach. The thesis is based on an existing store building (building class Br2 and occupancy class 2B) where Tyréns AB has determined a fire exposure specific for the store building, which is used to simulate 30 minutes of fire.

  7. 5. DIMENSIONERING AV TRÄTAKSTOLAR VID BRANDFALL : Enligt Kategori R30, R60

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Ivan Sido; Martin Kassar; Reem Bassi; [2021]
    Nyckelord :Roof; fire; truss; timber; structures; trusses; load; retardant; gypsum; loads;

    Sammanfattning : The following project work studies trusses and roof structures and their performance during a fire in terms of rules and requirements that needs to be considered. Determination of how resistant truss or roof construction is still heavily dependent on the subjective experience and assessment of professional. LÄS MER
