  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. Quantification of tribological effects in expansion fasteners

    University essay from KTH/Materialvetenskap

    Author : Nicolò Drahorad; [2019]
    Keywords : post-installed anchors; civil construction; tribology; antifriction coatings;

    Abstract : Post-installed anchors for civil construction are elements that ensure the integrity of building structures even under the most severe static, seismic and shock loadings. Despite the high popularity of this technology in construction sites all over the world, the current state of knowledge is limited and there is still a great potential for significant improvements.

  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. Reduction of Vertical Acceleration in High-speed Railway Bridges Using Post-installed Viscous Dampers : A case study of the Bothnia Line

    University essay from KTH/Bro- och stålbyggnad

    Author : Sarah Rådeström; Viktor Tell; [2014]
    Keywords : Structural dynamics; viscous dampers; high-speed trains; resonance; bridge design; bridge construction; Strukturdynamik; viskösa dämpare; höghastighetståg; resonans; brokonstruktion;

    Abstract : Several of the bridges along the Bothnia railway line do not fulfill the requirements regarding vertical accelerations that are stated in current design codes. The acceleration of the bridges needs to be reduced, in order to make the Bothnia line suitable for high speed railway traffic. READ MORE

  6. 5. Load capacity of anchorage to concrete at nuclear facilities : Numerical studies of headed studs and expansion anchors

    University essay from KTH/Betongbyggnad

    Author : Daniel Eriksson; Tobias Gasch; [2011]
    Keywords : anchor plates; headed studs; expansion anchors; concrete; finite element analysis; non-linear material models; failure envelopes;

    Abstract : The aim of this thesis was to study the load bearing capacity of anchor plates, used for anchorage to concrete located at nuclear facilities. Two different type of anchor plates were examined, which together constitute the majority of the anchor plates used at Forsmark nuclear facility in Sweden. READ MORE
