  1. 1. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

    Författare :Valbona Mara; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

    Sammanfattning : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. LÄS MER

  3. 2. Fibre reinforced polymer bridge decks: Sustainability and a novel panel-level connection

    Författare :Valbona Mara; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Sustainability; LCA; Life-cycle assessment; FRP deck; LCC; Life-cycle cost; Connection;

    Sammanfattning : Fibre reinforced polymer (FRP) bridge decks have emerged as a competitive alternative to traditional decking solutions for the refurbishment of existing bridges, as well as the construction of new ones, in the past two decades. FRP decks offer inherent properties such as light weight, high strength and high resistance to aggressive environments. LÄS MER

  4. 3. Bridge Edge Beams : LCCA and Structural Analysis for the Evaluation of New Concepts

    Författare :José Javier Veganzones Muñoz; Lars Pettersson; Costin Pacoste; Raid Karoumi; Håkan Sundquist; Morgan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Bridge edge beams in Sweden may involve up to 60% of the life-cyclemeasure costs incurred along the road bridge’s life span. Moreover, usercosts as means of traffic disturbances are caused. Consequently, the SwedishTransport Administration started a project to find better alternativeedge beam design proposals for the society. LÄS MER

  5. 4. Laser-welded corrugated core steel sandwich bridge decks

    Författare :Peter Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; steel sandwich; Bridge deck; corrugated core; laser-weld;

    Sammanfattning : Steel bridge decks are often used for applications when a lightweight structure is sought for. Conventional orthotropic steel decks suffers from drawbacks in several aspects, including high production costs and durability problems. LÄS MER

  7. 5. Bridge Monitoring to Allow for Reliable Dynamic FE Modelling : A Case Study of the New Årsta Railway Bridge

    Författare :Johan Wiberg; Håkan Sundquist; Raid Karoumi; Björn Paulsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge monitoring; FE modelling; signal analysis; torsion; warping; modulus of elasticity; natural frequency; damping; finite differences; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Today’s bridge design work in many cases demands a trustworthy dynamic analysis instead of using the traditional dynamic amplification factors. In this thesis a reliable 3D Bernoulli-Euler beam finite element model of the New Årsta Railway Bridge was prepared for thorough dynamic analysis using in situ bridge monitoring for correlation.
