  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. Strengthening of non-composite bridges by Partial Composite Action

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

    Författare :Johan Tjernberg; [2022]
    Nyckelord :Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Sammanfattning : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  4. 3. Concrete girders or steel trusses constituting the foundation under a building? : A comparison regarding the block Forskaren in Stockholm

    M1-uppsats, KTH/Byggteknik och design

    Författare :Berta Moshye; Nancy Shlimon; [2020]
    Nyckelord :LCA; Concrete girders; Steel trusses; LCA; Betongbalkar; Stålfackverk;

    Sammanfattning : Hagastaden is a new district in Stockholm that is growing, and many structures are being built. Kv Forskaren, a funnel-like office building, will be built above the Haga tunnel in an ongoing project. LÄS MER

  5. 4. Klimatoptimering av broar - Åtgärder vid projektering för reducering av växthusgasutsläpp med LCA

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

    Författare :Carljohan Jörnland; Jenny Henriksson; [2018]

    Sammanfattning : In 2017 the Swedish Parliament implemented a new national goal for limiting climate change. The goal is to have zero net emissions of greenhouse gases by year 2045 which will ultimately lead to negative net emissions. LÄS MER

  7. 5. Achieving Composite Action in Existing Bridges : With post-installed shear connectors

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

    Författare :David Olsson; [2017]
    Nyckelord :Shear connector; Composite action; post-installed; strengthening; Pitsund Bridge; coiled spring pins; Skjuvförbindare; Samverkansbroar; förstärkningsarbete; Pitsundsbron; spiralbult;

    Sammanfattning : The increased amount of traffic combined with higher traffic loads leads to many existing bridges needing strengthening in the future to ensure their expected lifespan. This means the bridge owners will be focusing more on strengthening projects and smart solutions will be crucial for preserving a healthy bridge stock. LÄS MER
