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

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

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

    Abstract : 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. READ MORE

  3. 22. Virtual Sensing for Fatigue Assessment of the Rautasjokk Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Sara Lundman; Patrick Parnéus; [2018]
    Keywords : Fatigue Assessment; Virtual Sensing; Steel Bridges; Eurocode; Field Monitoring; Finite Element Model;

    Abstract : This thesis treats virtual sensing for fatigue assessment of steel bridges. The purpose is to develop avirtual sensing method to use in the fatigue assessment process. The aim for the virtual sensing method is to only depend on strain measurements located on the bridge structure. READ MORE

  4. 23. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system

    University essay from KTH/Bro- och stålbyggnad

    Author : Hamad El Hamad; Furkan Tanhan; [2018]
    Keywords : Movable scaffolding system; MSS; Incremental launching; post-tension; prestress; slen- derness; box-girder; Stockholm Bypass; Movable scaffolding system; MSS; Etappvis lansering; efterspänning; förspänning; slankhet; box-girder; Förbifart Stockholm;

    Abstract : When designing a bridge it is of high importance that the geometry for the cross section is optimized for the structure. This is partly due to the influence of the amount of material needed and its impact on the budget and environment. READ MORE

  5. 24. Model-Free Damage Detection for a Small-Scale Steel Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Aaron Ruffels; [2018]
    Keywords : damage detection; structural health monitoring; machine learning; artificial neural network; model bridge;

    Abstract : Around the world bridges are ageing. In Europe approximately two thirds of all railway bridges are over 50 years old. As these structures age, it becomes increasingly important that they are properly maintained. If damage remains undetected this can lead to premature replacement which can have major financial and environmental costs. READ MORE

  6. 25. Strength simulations of tension bars for heavy lifting

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Arvid Hoikka; [2018]
    Keywords : Strength simulations; FEM; CAD-modelling; ABAQUS; Hållfasthetssimulering; FEM; CAD-modellering; ABAQUS;

    Abstract : Proplate, a world leading company, is expert on volume-based cutting and machining of both ordinary steel as well as stainless steel. One of Proplate’s mayor products is tension bars, which is a component made to balance high forces and give stability to structures such as cranes, buildings, bridges and much more. READ MORE
