  1. 11. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics

    Författare :Linus Andersson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduced order modeling; Substructuring; Nonlinear dynamics; Geometrically nonlinear; Modal derivatives; Blast loading; Soft-body impact; Glass structures;

    Sammanfattning : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. LÄS MER

  3. 12. Protecting food with poison : Exploring ecotoxicity of agrochemicals and pharmaceuticals

    Författare :Oskar Nyberg; Michael Tedengren; Peter Fantke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCA; ecotoxicology; uncertainty; antibiotics; aquaculture; pesticides; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Chemicals are being emitted into the environment through human activities, such as agriculture or animal husbandry. Emissions can either occur intentionally, as pesticide application of crops, or inadvertently, such as pharmaceutical residues in wastewater effluents. LÄS MER

  4. 13. Stainless steel box columns in fire : analysis and design recommendations

    Författare :Björn Uppfeldt; Olivier Vassart; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The use of stainless steel in buildings is small but increasing, mainly due to the low maintenance costs, favourable corrosion resistance and aesthetic appearance. It is well known that stainless steel also performs better than carbon steel at elevated temperatures. LÄS MER

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

    Författare :William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 15. Verktyg för optimering av byggtorkning

    Författare :Peter Brander; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; konstroller; fukt; kostnader; byggkonstruktioner; byggnadskonstruktion; controls; tools; system; risks; costs; Building materials; optimizing; drying; Building construction; byggnadsmaterial; moisture; byggtorkning; verktyg;

    Sammanfattning : För att bättre kunna kostnadsoptimera byggtorkningar har ett optimeringsverktyg innefattande ett antal olika beräknings och bedömningsparametrar tagits fram. Byggtorkning innefattar stora kostnader för energi, provisorier och kontroller. LÄS MER
