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. Partiell samverkan i KL-träkonstruktioner

   Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Jesper Lagerström; [2022]
   Nyckelord :Partiell samverkan träkonstruktion dubbelgängad;

   Sammanfattning : This is a study of partial composite action in timber constructions. The aim was to determine a method for calculating the flexural rigidity also known as bending stiffness in CLT-constructions made of CLT and wooden latches with screw connectors. The chosen method became a combination of Eurocode 5 and mathematical models. LÄS MER

4. 3. 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.

5. 4. Timber-steel hybrid structures with shear-key connections

   Master-uppsats, KTH/Byggnadsmaterial

   Författare :Tianxiang Wang; Yue Wang; [2019]
   Nyckelord :Hybrid structures; shear-key connections; glulam beam; analytical calculation; simulations; experiments.;

   Sammanfattning : Large-dimensional wooden products are highly demanded within the construction sector. Theprimary motive of the thesis is to find a solution to connect small timber elements by meansof special steel devices. LÄS MER

7. 5. 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
