  1. 1. Temperature distribution in air tight cavities of steel framed modular buildings when exposed to fire

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser; Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Elin Bergroth; Greta Torstensson; [2019]
    Keywords : Cavities; fire furnace; fire test; modular building; steel; TASEF; Brandugn; brandtest; hålrum; modulbyggnader; stål; TASEF;

    Abstract : A common way to construct large buildings is by assemble prefabricated modules around a load bearing steel construction. However, if a fire occurs these buildings can be subject to a rapid fire spread due to its cellular nature. READ MORE

  3. 2. Simulation and Analysis of Ultrasonic Wave Propagation in Pre-stressed Screws

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Erik Andrén; [2019]
    Keywords : ;

    Abstract : The use of ultrasound to measure preload in screws and bolts has been studied quite frequently the last decades. The technique is based on establishing a relationship between preload and change in time of flight (TOF) for an ultrasonic pulse propagating back and forth through a screw. READ MORE

  4. 3. Analysis of a Prefabricated Concrete Skew Angle Slab Bridge

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY); Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Pär Bengtsson; Johan Wallin; [2019]
    Keywords : Finite Element Model; Skew Angle Slabs; Slab Bridge; Prefabrication;

    Abstract : Prefabricated concrete elements are widely used in the construction industry today. With advantages such as time savings, increased safety at the construction site and minimized material usage, prefab becomes a major challenger to the traditional on-site casting construction method.

  5. 4. 3D Finite Element Modelling of ICRH in JET

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Björn Ljungberg; [2019]
    Keywords : ;

    Abstract : This master's thesis assesses the possibility of using the nite element method to solve the electromagneticwave equation in a fusion plasma in 3D. In particular, the frequency is chosen to match that of ioncyclotron resonance heating in the fusion experiment JET. READ MORE

  6. 5. Dynamic Design of Bridges on High-Speed Railway Lines

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE
