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. Strengthening of non-composite bridges by Partial Composite Action

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

   Sammanfattning : 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.

4. 3. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Simon Stahlin; [2019]
   Nyckelord :composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

   Sammanfattning : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. LÄS MER

5. 4. Achieving Composite Action in Existing Bridges : With post-installed shear connectors

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :David Olsson; [2017]
   Nyckelord :Shear connector; Composite action; post-installed; strengthening; Pitsund Bridge; coiled spring pins; Skjuvförbindare; Samverkansbroar; förstärkningsarbete; Pitsundsbron; spiralbult;

   Sammanfattning : The increased amount of traffic combined with higher traffic loads leads to many existing bridges needing strengthening in the future to ensure their expected lifespan. This means the bridge owners will be focusing more on strengthening projects and smart solutions will be crucial for preserving a healthy bridge stock. LÄS MER
