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. Hybrid bridge deck of timber and corrugated steel plates

   University essay from KTH/Byggnadsmaterial

   Author : Muze Lu; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

4. 3. 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

5. 4. 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

6. 5. Towards Green Steel Circular Business Models : Exploring Barriers and Business Model configurations

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Author : Robin Bergman; Rasmus Rönnqvist; [2023]
   Keywords : Steel industry; Green Steel; Circular Business Models; Adoption Barriers; Business Model configurations;

   Abstract : Purpose - The aim of the study is to further bridge the gap regarding adoption of Circular Business Models (CBM) more specifically in this case, the barriers to the adoption of Green Steel CBMs, and how Business Models (BM) can be configured for the adoption of Green Steel CBMs. Method - The research questions in the study were answered through a thematic analysis based on a three-phase data collection consisting of two informal meetings with industry specialists and 25 semi-structured interviews, followed by eleven additional interviews from a Green Steel conference to validate the findings of the semi-structured interviews.
