  1. 1. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Fatiha El Azrak; [2023]
    Nyckelord :;

    Sammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

  3. 2. Explaining the dynamics of exchange rate volatility

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Jacob Tjerneld; Hampus Lööw; [2022]
    Nyckelord :Exchange Rates; Volatility; GARCH; Heteroskedasticity; Time Series Analysis.; Business and Economics;

    Sammanfattning : This research examines the volatility of the Swedish krona in regards to the Euro and US-dollar exchange rate, using both daily and monthly data ranging from the beginning of 2000 until 2022. Using this time span allows us to update previous literature on exchange rate volatility, and also incorporates recent economic events such as the great financial crisis of 2008, the 2020 covid-pandemic and the geopolitical uncertainty in Europe following Russia's invasion of Ukraine.

  4. 3. Modellförsök avseende bergspänningars betydelse för spännvidd av valv

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Minna Larsson; Klara Skoog; [2020]
    Nyckelord :arch; arching; span of arch; rock stress; rock reinforcement; rock bolt; valv; valvbildning; spännvidd; bergspänning; bergförstärkning; bergbult;

    Sammanfattning : Tunnels and anthropogenic underground cavities are a very natural part of our everyday modern life. Especially in larger cities such as Stockholm where the infrastructure reaches far above ground level as well as deep below the surface. LÄS MER

  5. 4. Behavior prediction of concrete dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Isak Nilsson; Leonard Sandström; [2020]
    Nyckelord :Concrete dams; dam monitoring; dam safety; measurement evaluation; databased models i;

    Sammanfattning : As many dams were built around 1950, the expected life span of these dams are about tobe reached. With this, the need for monitoring and increased understanding of the damsstructural integrity increases. In order to prevent failures, two warning signals are defined;alert and alarm. LÄS MER

  7. 5. Variations in dynamic properties of a steel arch footbridge : An experimental study

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Martin Földhazy; [2018]
    Nyckelord :Damping ratio; Natural frequencies; Temperature; static mass; Human structure interaction;

    Sammanfattning : This study separately investigates how temperature as well as two real load-situations affects the modal damping ratio and natural frequencies of a 64.9m span steel arch footbridge. Measurements of acceleration have been completed which covers a temperature span of  to . LÄS MER
