  1. 1. Analytiska modeller för beräkning av tjällaster mot spontkonstruktioner

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :STAFFAN NORRTHON RISBERG; NAIMA OZIMS; [2023]
    Nyckelord :;

    Sammanfattning : I kalla klimat kan stödkonstruktioner utsättas för lastökningar till följd av tjälande jord. Tjälen bildas när vattnet i jorden fryser, och leder ofta till en volymexpansion i marken. Om tjälexpansionen förhindras bildas ett tjältryck, som kan bli så pass kraftigt att stödkonstruktioner riskerar att gå till brott. LÄS MER

  3. 2. Moment-resisting connections for glulam using birch plywood : An experimental study on both mechanical and adhesive connections

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Jonatan Ringaby; [2022]
    Nyckelord :;

    Sammanfattning : The aim of this study was to investigate the load-bearing capacity and stiffness of mechanical and adhesively bonded connections in timber structures with gusset plates made of birch plywood, as a preliminary study for potential future use in long-span timber structures which could reduce the environmental impact of the building sector by substituting steel with wood products in moment-resisting connections. Birch plywood was chosen for this study due to its high bending strength in comparison to plywood made of softwoods and its availability on the market. LÄS MER

  4. 3. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)

    Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :David Ottosson; [2021]
    Nyckelord :GFRP; Durability; SLS; Atena;

    Sammanfattning : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. LÄS MER

  5. 4. Design and Analysis of a Generic Fixture for Physical Squeak and Rattle Prediction

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Darshan Bandihalli Mahalingaiah; Ajayvarma Sagi; [2020]
    Nyckelord :Finite Element Analysis; Topology Optimization; Design and analysis; Squeak and Rattle; Biw; Cockpit.;

    Sammanfattning : The thesis work investigates the possibility of replacing the Body-In-White (BIW) sections used in a physical test with a fixture. Volvo-cars perform several sub-system tests on its car components taken from various car models for different issues. LÄS MER

  7. 5. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

    Master-uppsats, KTH/Betongbyggnad

    Författare :Viktor Peterson; Zihao Wang; [2020]
    Nyckelord :Non-linear time-history analysis; non-linear pushover analysis; N2- method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings iv;

    Sammanfattning : A large amount of low-rise unreinforced masonry structures (URM) can be foundin Groningen, the Netherlands. More and more induced earthquakes with shortduration have been detected in this region due to gas exploitation. LÄS MER
