  1. 1. Reduction of Explosion Effects by Use of a Sandwich Wall

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Annie Bohman; [2023]
    Nyckelord :Explosion Blast load Sandwich wall Energy absorption; Technology and Engineering;

    Sammanfattning : It was recently decided that a new hospital is to be built in Växjö. It is important that hospitals can be utilised no matter the circumstances, even in situations of threat. New reports have been published concerning how hospitals are to be designed. In this, it is mentioned that explosions are a threat that should be considered. LÄS MER

  3. 2. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    Master-uppsats, KTH/Betongbyggnad

    Författare :Anton Frank; Andreas Fristedt; [2021]
    Nyckelord :Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Sammanfattning : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  4. 3. Simulations of Safety Aspects for Occpuants in Mine Blast Events

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Pontus Nordström; [2019]
    Nyckelord :;

    Sammanfattning : Underbody mine blasts are events during which massive amounts of energy is transferred to a vehicle and its occupants during a very short time. The occupants are usually protected by both external (armor) and internal (seat suspension/belts etc.) features. LÄS MER

  5. 4. Feeling the zeros : Modeling individual responses, measured against time, to treatment of chronic myeloid leukemia.

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Anna Warnqvist; [2017]
    Nyckelord :two-level modeling; censored modeling; chronic myeloid leukemia;

    Sammanfattning : In this paper response curves of patients with chronic myeloid leukemia are modeled using one and two-level censored models. Two-level models (also called mixed models) allow random effects and censored models are used to account for the large amount of values too small to be detected. LÄS MER

  7. 5. Response of Buildings Exposed to Blast Load - Method Evaluation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Carl Löfquist; [2016]
    Nyckelord :Explosion; Blast Wave; Impulse; Rayleigh-Ritz metod; Ritz vectors; Computational effeciency; Modal Reduction; Eurocode; Technology and Engineering;

    Sammanfattning : Due to accidental external explosions ,which is not handle in the Eurocodes, are structural designers looking for other ways to design loads for external loads due to explosions. This combined with lighter building structures is a reason to address the issues of analysing the dynamic behavior of buildings subjected to air blasts from these extreme situations. LÄS MER
