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. Harmonised traffic load model between Eurocode 1 - part 2 (EN 1991-2) and TRV specifications : A pilot study on reinforced concrete portal frame bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Mubashar Amir Ablahad; Nuredin Rasslan; [2023]
   Keywords : ;

   Abstract : The advancement of society has led to an increase in demand for infrastructure, particularly bridges, which are designed in accordance with different design codes. In Sweden, bridge design adheres to the Eurocode and national code (TRV specifications), with the most adverse scenario of the two codes determining the basis for bridge design. READ MORE

4. 3. Mapping of Dependent Structural Responses on a Prestressed Concrete Bridge using Machine Learning Regression Analysis and Historical Data : A Comparison of Different Non-linear Regression Approaches

   University essay from Umeå universitet/Institutionen för datavetenskap

   Author : Vedad Coric; [2023]
   Keywords : Prestressed Concrete Bridges; Structural health Monitoring; Machine Learning; Regression analysis; Infrastructure management;

   Abstract : Prestressed concrete bridges are susceptible to deterioration over time which might significantly affect their capacity and overall performance. In previous decades, infrastructure owners have found that continuous monitoring of these assets is a valuable tool for their management as it facilitates the decision-making process regarding the intervention strategies required.

5. 4. Analyzing a New Method for Estimating Strength Classes in Existing RC Structures

   University essay from KTH/Transportplanering

   Author : Gabriel Matli; Veronica Soulaka; [2023]
   Keywords : ;

   Abstract : This master thesis focuses on validating the Graphical Concrete Strength Class (GCSC) method on a large scale. The GCSC method is an empirical approach for assessing the concrete strength class of existing reinforced concrete structures. READ MORE

6. 5. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Alex Eriksson; [2023]
   Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

   Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.
