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. 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.

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

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

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

   Abstract : 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. READ MORE

5. 4. Strengthening of I-girder bridges : Fatigue endurance

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

   Author : Olle Edström; [2016]
   Keywords : ;

   Abstract : Structures have always been subjected to the detrimental consequences of the fatigue phenomenon. The consequences due to this damaging effects leads to crack initiation and the ultimate result being complete failure. Fatigue appears on structures that has to endure fluctuating loads over a long period. READ MORE

6. 5. A New Bridge Proposal - Road Bridge with a Cross-Laminated Timber Slab

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Hannes Behrens; Per Benner; [2015]
   Keywords : timber bridge; steel bridge; short construction time; steel-concrete composite bridge; bridge design; Cross-laminated timber; CLT; Technology and Engineering;

   Abstract : In this thesis, a new bridge type is proposed. It is a steel bridge with a slab of cross-laminated timber elements. The bridge is intended for road traffic, and it has a span length of 26 m. It aims to be competitive when a short construction time is important. READ MORE
