  2. 6. Toward a reliability framework for the observational method

    Author : Johan Spross; Stefan Larsson; Fredrik Johansson; Rasmus Müller; John Harrison; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; observational method; Eurocode 7; structural safety; reliability analysis; dam safety; Bergmekanik; observationsmetoden; Eurokod 7; sannolikhetsbaserad dimensionering; dammsäkerhet; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Constructing sustainable structures in rock that satisfy all predefined technical specifications requires rational and effective construction methods. When the geotechnical behaviour is hard to predict, the Euro­pean design code, Eurocode 7, suggests application of the observational method to verify that the performance is acceptable. READ MORE

  4. 7. 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

  5. 8. Time-dependent effects in the analysis and design of slender concrete compression members

    Author : Bo Westerberg; Jonas Holmgren; Sven Thelandersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Abstract : The report deals with the effect of time-dependent concrete properties in the analysis and design of slender compression members. The main focus is on how to take these effects into account in nonlinear analysis, not on the properties as such in a materials science perspective. READ MORE

  6. 9. Optimal design solutions of road bridges considering embedded environmental impact and cost

    Author : Elisa Khouri Chalouhi; Raid Karoumi; Costin Pacoste; Mario Plos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural optimization; Automated design; Road bridges; Environmental impact; Global warming potential; Cost; Overhang bridge slab; Edge beam; Composite bridges; Strukturell optimering; Automatiserad dimensionering; Vägbroar; Miljöpåverkan; Global uppvärmningspotential; Kostnad; Överhängande broplatta; Kantbalk; Kompositbryggor.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Continuous urbanization and population growth are increasing the demand for transportation infrastructure such as bridges. The construction of these structures represents a significant economic investment for public authorities; moreover, the construction sector accounts for a big portion of CO2 emissions. READ MORE

  7. 10. Aspects of Sorption Processes in Thermosiphon and in Falling Film Arrangements

    Author : Henrik Kockum; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transfer; turbulence; falling film; heat transfer; entropy generation; pressure drop; restriction; friction; void fraction; two-phase flow; thermosiphon; sorption; heat pump; model; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : A study concerning closure relations pertinent to the design of sorption equipment of absorption heat pumps has been undertaken. Specifically, thermosiphon and vertical falling film arrangements were studied. READ MORE
