Dynamic properties of Stress-laminated Timber Bridges
Johansen, Sigve Ostad; Martinsen, Lavina Kristine (Master thesis, 2021) -
Earthquake response of bridges supported by vertical and batter piles accounting for nonlinear soil-structure interaction
Cemalovic, Miran (Doctoral theses at NTNU;2023:197, Doctoral thesis, 2023)Around the world, large structures such as bridges, harbours and skyscrapers, are built in areas where the seismic risk is relatively high. In many cases, these structures are supported by deep foundations due to overlaying ... -
Genetic algorithm for identifying train causing greatest fatigue damage in railway bridges
Bø, Anita; Knudsen, Nora (Master thesis, 2019)Den norske naturen, med sine mange fjell, daler og fjorder, gjør broer til viktige komponenter i landets jernbanenettverk. Jernbanebroene er påkjent av gjen- tatte dynamiske laster, som en følge av at tog kjører over ... -
Global Analysis of Submerged Floating Tunnels Under Hydrodynamic Loading
Mascella, Martin (Master thesis, 2020)This master’s thesis includes several preliminary designs of Submerged Floating Tunnels (SFT) and its responses to hydrodynamic loading. SFT is a never built transport structure, which can be use for crossing lakes, straights ... -
Heuristic models for wear prediction and dynamic-based condition monitoring techniques in pantograph-catenary interaction
Derosa, Stefano (Doctoral theses at NTNU;2020:381, Doctoral thesis, 2020)Railway catenaries are key components of electric railways, representing for the trains both their power source and their performance limiter. Although the amount of electrified railways is noticeably lower than the ... -
Konseptuell konstruksjonsdesign av gangbro med seilløp
Nærum, Haldis Sandøy (Master thesis, 2020)Studiet denne rapporten omhandler ble initiert av ønsket om å gjennomføre et konseptutviklingsstudie av en fotgjengerbro, muligheten til å undersøke innovative og bærekraftige løsninger samt å levere et innslag til konferansen ... -
Load model of historic traffic for fatigue life estimation of Norwegian railway bridges
Frøseth, Gunnstein T. (Doctoral theses at NTNU;2019:73, Doctoral thesis, 2019)Material fatigue is the primary damage mechanism in steel railway bridges and ultimately causes material fracture and eventually component and system failure. It is essential that the infrastructure owner can predict and ... -
Parametric Structural Analysis and Development of Aluminium Connectors in Timber Gridshells
Myrnes, Ragnhild; Skeide, Kristin Kilvik (Master thesis, 2020)Gitterskallkonstruksjoner har tradisjonelt blitt bygd opp av rette stålelementer, sveiset eller boltet til stålforbindere. På grunn av miljøaspekter, utvikling av trelastprodukter, økt fokus på tre som byggemateriale både ... -
