  1. 1. Structural evaluation of concrete buildings considering bearing capacity, load combinations, and safety regulations : Analyzing the difference design methods used in old Swedish Norms “Statliga betongbestämmelser 1949, BBK79, Eurocode”

    Master-uppsats, KTH/Betongbyggnad

    Författare :Abdallah El-Sanei; Najim Abdallah Mohammad; [2020]
    Nyckelord :concrete; codes; design; load - combinations; Betong; koder; last - kombination;

    Sammanfattning : Design regulations for concrete structures differ through time and place. Throughout the years design regulations have been changed and adjusted for improvement and to ensure safe and secured structures. LÄS MER

  3. 2. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

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

    Författare :Brianna Kilberg; [2020]
    Nyckelord :Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Sammanfattning : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. LÄS MER

  4. 3. Solving a highly constrained multi-level container loading problem from practice

    Kandidat-uppsats, Linköpings universitet/Optimeringslära; Linköpings universitet/Tekniska fakulteten

    Författare :Jonas Olsson; [2017]
    Nyckelord :container loading; 3D packing; real-world application; heuristic; genetic algorithm;

    Sammanfattning : The container loading problem considered in this thesis is to determine placements of a set of packages within one or multiple shipping containers. Smaller packages are consolidated on pallets prior to being loaded in the shipping containers together with larger packages. LÄS MER

  5. 4. The impact of fire development on design resistance of structures

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

    Författare :Catrin Eberius; Kristin Fjällström; [2017]
    Nyckelord :Large compartments; temperature- time curves; travelling fires; simplified fire models; fire development;

    Sammanfattning : The current design methods used to determine fire progression and temperature-time development in fire compartments today are being questioned to not give accurate results in large and complex enclosures (larger than 500 m2). The established design methods proposed by Eurocode and used by fire safety engineers today are primarily the standard temperature-time curve and the parametric temperature-time curves. LÄS MER

  7. 5. Experimental verification of an instrument to test flooring materials.

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Rony Philip; [2017]
    Nyckelord :Fluid model; coefficients of the floor; linear dynamics; Matlab; least square method.;

    Sammanfattning : The focus of the project is to validate the fluid model with different flooring materials and the measurements of an instrument to test flooring materials and its force attenuating capabilities using mathematical models to describe the signature and coefficients of the floor.As a part of improving the knowledge about the linear dynamics of vibrations involved during the sudden impact caused on hip bones of elderly people during fall.
