  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. Momentbelastade stål-till-KLträanslutningar för utomhusmiljöer

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Shafiqa Akbari; Zara Mohseni; [2024]
    Nyckelord :momentbelastade korslimmat träanslutningar; KL-träanslutningar; cyklisk momentbelastning; fuktkvot; fuktkvot variation.;

    Sammanfattning : Rapid climate changes have increased the importance of environmental concerns,particularly within the construction industry, which faces substantial challenges to reduceits environmental footprint. Shifting from high-emission building materials to sustainablealternatives stands as a critical strategy to reduce climate impact. LÄS MER

  4. 3. Hybrid bridge deck of timber and corrugated steel plates

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Muze Lu; [2023]
    Nyckelord :;

    Sammanfattning : Over the years, hybrid structures composed of timber and steel have become a potential alternative to conventional solutions. Recently, corrugated steel plate (CSP) has become more and more popular in structures such as shear walls and roofs due to its favorable mechanical properties. LÄS MER

  5. 4. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Charlotte Jaeger; [2023]
    Nyckelord :;

    Sammanfattning : This study focuses on exploring a novel timber-to-timber joint using a steel hinge connection (in this work also referred to as door-hinge joint) for pedestrian timber bridges. To conduct the cross-section design of the structural bridge members, a numerical model was developed to determine the internal forces. LÄS MER

  7. 5. Life extension of welded steel details in bridges

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Zhelei Jin; [2023]
    Nyckelord :Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Sammanfattning : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. LÄS MER
