  1. 1. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)

    Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :David Ottosson; [2021]
    Nyckelord :GFRP; Durability; SLS; Atena;

    Sammanfattning : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. 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. Böjknäckning och utböjning av VKR-profiler

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Mustafa Ahmed; Khaldoon Barka; [2020]
    Nyckelord :VKR KKR-Profiles; buckling; column buckling; deflection; bendingcracking; windload; Eurokod; Abaqus; Excel; Mathcad; FE-analysis;

    Sammanfattning : This work has been done in collaboration with Northpower Stålhallar AB. The work is concentrating on column buckling, wind load and deflection of steel columns made of VKR profiles. VKR profiles are steel profiles that are hot-rolled structural pipes having a rectangular section. LÄS MER

  5. 4. Impact loads on the self-elevating unit during jacking operation

    H-uppsats,

    Författare :Viktor Daun; Fredrik Olsson; [2019-07-03]
    Nyckelord :Farkostteknik; Vehicle Engineering;

    Sammanfattning : The renewable energy resource of offshore wind is believed to have a great potential in playing an essential role on the future energy market in Europe, but there are complications such as harsh weather and low accessibility. To manage this, most offshore wind turbines of today are installed and maintained using self-elevating units (SEUs). LÄS MER

  7. 5. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

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

    Författare :Simon Stahlin; [2019]
    Nyckelord :composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

    Sammanfattning : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. LÄS MER
