  1. 1. FE-Modelling of Composite Girder tests

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

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 2. Evaluation of a computational method for natural fiber-reinforced plastics

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anna Lim; [2023]
    Nyckelord :PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Sammanfattning : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. LÄS MER

  4. 3. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Moa Nolinder; [2023]
    Nyckelord :;

    Sammanfattning : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. LÄS MER

  5. 4. Kritiska vippningslaster för kompositbalkar/lättbalkar av trä

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Jemy Abdalnour; Mohamed Ibrahim Abdirahman; [2023]
    Nyckelord :;

    Sammanfattning : This thesis has focused on the calculation of critical loads for lateral torsional buckling forthree selected wood-based composite beams with varying heights based on the availableMasonite Beams standard range. The main objective has been to investigate and compare ahand calculation model with the recommended method in Eurocode 5, as well as comparethem with results from finite element analysis. LÄS MER

  7. 5. Mechanical and thermal buckling analysis of laminated composite plates

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Aswin Paremmal; Roopak Kuruthukulangara Varghese; [2023]
    Nyckelord :composite material; Mechanical Buckling; Buckling analysis;

    Sammanfattning : Composite laminated structures have many application fields such as aerospace, civil, marine, bio medical, transportation, and mechanical engineering because of their convenience in handling, and very good mechanical properties. Buckling behavior of laminated composite plates subjected to plane loads is indeed an important consideration in the primary design of aircraft and launch vehicle components. LÄS MER
