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. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

   University essay from KTH/Bro- och stålbyggnad

   Author : Moa Nolinder; [2023]
   Keywords : ;

   Abstract : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. READ MORE

4. 3. Strengthening of non-composite bridges by Partial Composite Action

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

   Author : Johan Tjernberg; [2022]
   Keywords : Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

   Abstract : 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.

5. 4. Cost optimization of composite bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Markus Lythell; Jonathan Stenberg; [2020]
   Keywords : Composite bridge; Optimization algorithm; Pattern search; Cost optimization; MATLAB; Samverkansbroar; Optimeringsalgoritmer; Pattern search; Kostnadsoptimering; MATLAB;

   Abstract : Today in most design offices the practice when designing infrastructure is to adopt a trial-and-error based approach. This means that one solution to the problem is evaluated and based on the results the design is altered. This process is then repeated until satisfactory results have been achieved. READ MORE

6. 5. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

   University essay from KTH/Bro- och stålbyggnad

   Author : DIEGO FERNANDEZ BARRERO; [2019]
   Keywords : Dynamics; soil-steel bridges; soil-structure interaction; model updating; PML; particle swarm; corrugated steel plates; frequency domain assurance criteria; parallel computing 2;

   Abstract : This master thesis covers the dynamic soil structure interaction of soil-steel culverts applyinga methodology based on the frequency domain response. At the first stage of this masterthesis, field tests were performed on one bridge using controlled excitation. READ MORE
