   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

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

   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
