  1. 1. FE-Modelling of Composite Girder tests

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Abstract : 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. READ MORE

  3. 2. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

    University essay from KTH/Byggnadsmaterial

    Author : Charlotte Jaeger; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Life extension of welded steel details in bridges

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Abstract : 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. READ MORE

  5. 4. Analysis of Footbridge Comfort Vibrations

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Niklas Thuresson; Henrik Ruuth; [2023]
    Keywords : footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

    Abstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE

  6. 5. Sustainable concrete bridges : An investigation of possible measures to reduce the climate impact

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Daniel Hugh; [2022]
    Keywords : Bridges; CO2; emission; cement; reinforcement; SCM; sustainability.;

    Abstract : The need of building new bridges is always existing in relation with the increase of infrastructureand transport needs. Bridge constructions have traditionally been associated with highconsumption of resources and large greenhouse gas emissions. READ MORE
