  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. African Climate Hazard Assessment - A composite index assessing national vulnerability to climate change

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Josefine Falk; Otto Fjelkner; [2023]
    Nyckelord :Composite Index; Climate Vulnerability; Assessment; African Nations; Acute Physical Hazards; Chronic Physical Hazards; Systemic Hazards; Exposure; Multidimensional Approach; Sensitivity; Adaptation; Indicators; Technology and Engineering;

    Sammanfattning : The study is compiled into a composite index for assessing the climate vulnerability of African nations. By employing a multidimensional approach, the index comprises nine distinctive hazards to examine a country’s sensitivity to climate change. LÄS MER

  4. 3. Global Analysis of a Tall Timber- Concrete Hybrid Structure Subjected to Wind Load : A Parametric Study of Different Hybrid Solutions

    Master-uppsats, KTH/Betongbyggnad

    Författare :Clara Youssef; Meriam Basilious; [2022]
    Nyckelord :;

    Sammanfattning :   Tall timber structures have received more attention in recent times as building withtimber contributes to environmental benefits in comparison to other building materials.Timber- concrete hybrid structures have become an alternative as previous investigationshave shown that building tall timber buildings implies complexities with regardsto sufficient stiffness and discomfort for occupants.

  5. 4. Partiell samverkan i KL-träkonstruktioner

    Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Jesper Lagerström; [2022]
    Nyckelord :Partiell samverkan träkonstruktion dubbelgängad;

    Sammanfattning : This is a study of partial composite action in timber constructions. The aim was to determine a method for calculating the flexural rigidity also known as bending stiffness in CLT-constructions made of CLT and wooden latches with screw connectors. The chosen method became a combination of Eurocode 5 and mathematical models. LÄS MER

  7. 5. 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.
