  1. 1. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Blahoslav Rataj; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. LÄS MER

  3. 2. Effects of cracking of coupling beams onhigh rise towers subjected to wind load

    Master-uppsats, KTH/Betongbyggnad

    Författare :Brook Worku Woldemikael; [2020]
    Nyckelord :Crack; reinforcement content; aspect ratio; shear deformation; joint flexibility; concrete grade; effective stiffness.; Sprickor; förstärkningsinnehåll; tvärsnittsförhållande; skjuvdeformation; ledflexibilitet; betongkvalitet; effektiv styvhet;

    Sammanfattning : In high rise towers, reinforced concrete elevator shafts with coupling beams are extensively used as a principal structural element to resist lateral loads. The lateral load resistance of the tower is dominantly dependent on the stiffness of the load-bearing walls, and coupling beams connecting them. LÄS MER

  4. 3. Designing radiation protection for a linear accelerator : using Monte carlo-simulations

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

    Författare :Jonatan Lindahl; [2019]
    Nyckelord :linac; linear accelerator; accelerator; mega voltage photons; spectra determination; high energy photons; Monte carlo; simulations; radiation transport; dose; radiation; radiation protection;

    Sammanfattning : The department of Radiation Sciences at Umeå University has obtained an old linear accelerator, intended for educational purposes. The goal of this thesis was to find proper reinforced radiation protection in an intended bunker (a room with thick concrete walls), to ensure that the radiation outside the bunker falls within acceptable levels.

  5. 4. Design of Thick Concrete Beams : Using Non-Linear FEM

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Daniel Mekonnen Teklemariam; Bennie Hamunzala; [2016]
    Nyckelord :Thick concrete beam; Capacity; Non-linear finite element analysis; Crack width; Load deformation response; Ultimate and Serviceability limit state.; Tjocka betongbalkar; Kapacitet; Icke-linjära finita element analys; Sprikvidd; Deformation; Brott-och bruksgränstillstånd;

    Sammanfattning : The experimental studies performed on the behaviour of very thick concrete beams subjected to static loads have revealed that the shear mechanisms play an important role in the overall response and failure behaviour. The aim of this thesis is to recommend suitable design methods for thick concrete beams subjected to off-centre static concentrated load according Eurocode 2 by using non-linear finite element analysis (NLFEA).

  7. 5. Sprickvidd nära armeringsjärn i betongbalkar.

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Fredrik Aronsson; Oskar Larsson; [2007]
    Nyckelord :corrosion; durability; concrete; crack; crack width; concrete cover; Technology and Engineering;

    Sammanfattning : When designing concrete structures, there are great demands made on quality and service life of the construction, and for this the size of concrete cover is crucial. The concrete cover protects the reinforcement bars from carburization and from infiltration of chlorides, which make them corrode. LÄS MER
