  1. 1. Drop-weight impact tests on reinforced concrete beams

    Master-uppsats, KTH/Betongbyggnad

    Författare :John Abdalnour; Milad Saliba; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. LÄS MER

  3. 2. Effekter av packning av finfilter i fyllningsdammar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Jonsson; [2023]
    Nyckelord :Fyllnadsdamm; Finfilter; Packningsgrad;

    Sammanfattning : There are over 10 000 dams in Sweden of various types and sizes. Most of the larger dams were built around 1950-1970 when the Swedish hydropower was expanded. Since then, the knowledge of engineering dam structures has increased and there are new guidelines for how a dam should be built. LÄS MER

  4. 3. Fallviktsförsök på skjuvarmerade betongbalkar

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Louise Atterling; My Widmark; [2022]
    Nyckelord :Concrete beams; impact load; dynamic load; shear reinforcement; shock load; vibrations; signals;

    Sammanfattning : Standards and regulations for dimensioning of load-bearing structures are based on the response of load-bearing structures subjected to loads without variation in time. In the event of an accidental load, e.g. a collision or explosion, causes the load to have a rapid variation in the time resulting in a dynamic response.

  5. 4. Undersökning av lågtemperaturegenskaper hos bitumen för asfaltbeläggningar med dynamisk skjuvreometer, DSR.

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

    Författare :Magid Badran; Ahmad Altarmazwi; [2022]
    Nyckelord :DSR; lågtemepraturegenskaper; BBR; reologi.; Technology and Engineering;

    Sammanfattning : The Dynamic Shear Rheometer, DSR, became central in connection with the launch of the Superpave methodology and is an instrument that can be used to assess asphalt properties. The instrument could at an early stage of the Superpave methodology not perform measurements at low temperatures and had to be supplemented with the device Bending Beam Rheometer, BBR, for that purpose.

  7. 5. FE-Modelling of a Joint for Cross-Laminated Timber

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Linus Ekhagen; [2021]
    Nyckelord :cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

    Sammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER
