  2. 1. On reliability-based design of rock tunnel support

    Author : William Bjureland; Stefan Larsson; Fredrik Johansson; Johan Spross; Lars Rosén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnation.; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Tunneling involves large uncertainties. Since 2009, design of rock tunnels in European countries should be performed in accordance with the Eurocodes. The main principle in the Eurocodes is that it must be shown in all design situations that no relevant limit state is exceeded. READ MORE

  4. 2. Rail Tunnel Evacuation

    Author : Karl Fridolf; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smoke; walking speed; flow rate of people; experiment; train; tunnel; metro; underground rail transportation system; evacuation; Human behavior in fire;

    Abstract : In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. READ MORE

  5. 3. Fire safety design of road tunnels

    Author : Jonatan Gehandler; Avdelningen för Brandteknik; []
    Keywords : HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE

  6. 4. On Subscale Flight Testing : Applications in Aircraft Conceptual Design

    Author : Alejandro Sobron; Petter Krus; David Lundström; Zdobyslaw Goraj; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence.

  7. 5. Reliability-based design of rock tunnel support

    Author : William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnad; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. READ MORE
