  1. 16. LCA and LCCA in the design of geotechnical engineering works

    Författare :Ida Samuelsson; Stefan Larsson; Johan Spross; Rasmus Rempling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Life Cycle Cost Analysis; climate impact; costs; geotechnical engineering; Livscykelanalys; Livscykelkostnadsanalys; klimatpåverkan; kostnader; geoteknik; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Geotechnical engineering works are part of almost all construction and infrastructure projects. The geotechnical engineering work contributes to the impact on the environment and gives rise to costs throughout its life cycle. LÄS MER

  3. 17. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

    Författare :Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. LÄS MER

  4. 18. Managing uncertainty in building acoustics : comparisons of predictions with the 12354 standards to measurements

    Författare :Christian Simmons; Eddy Gerretsen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; Teknikvetenskap; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : The thesis summarizes results of research on the uncertainty of standardized methods applied in the field of building acoustics, with respect to calculations as well as to measurements. Eight published papers are appended to the thesis. LÄS MER

  5. 19. Modelling the acoustic performance of slab tracks

    Författare :Jannik Theyssen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical modelling; railway noise; rolling noise; slab track; acoustic optimisation;

    Sammanfattning : Transport is a major contributor to anthropogenic greenhouse gas emissions. Railway transport has a small footprint compared to other means of transport. This is one reason for the construction of new high-speed railway lines world-wide. LÄS MER

  7. 20. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders

    Författare :Mirja Rothhämel; Jan Laue; Sven Knutsson; Craig Lake; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft soil; clay; silt; silty sand; soil stabilisation; hydraulic binder; cement; lime; by-product; cement kiln dust CKD ; cold climate; frost; freeze-thaw; laboratory test; field test; subsoil; road construction; feinkörninge Böden; Ton; Schluff; schluffiger Sand; Bodenstabilisierung; hydraulische Bindemittel; Zement; Kalk; Nebenprodukt; Zementofenstaub; kaltes Klima; Frost; Frost-Tau; Laborversuche; Feldversuche; Verkehrsbau; Dauerhaftigkeit; finkornig jord; lera; silt; siltig sand; jordstabilisering; hydraulisk bindemedel; cement; kalk; biprodukt; cement kiln dust CKD ; kallt klimat; frost; frysning-tining; laboratorieanalyser; fältförsök; vägterrass; Geoteknik; Soil Mechanics;

    Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER
