  2. 1. Composite Bridges : Innovative ways of achieving composite action

    Author : Robert Hällmark; Peter Collin; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite action; bridges; steel; concrete; shear connectors; prefabrication; coiled spring pins; shear studs; post-installation; design guidance; Structural Engineering; Konstruktionsteknik;

    Abstract : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. READ MORE

  5. 3. Fatigue of steel bridges : New structural details and the implementation of high strength steel

    Author : Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high strength steel; fatigue; steel bridges; steel and concrete composite bridges; new structural details; linear elastic fracture mechanics; effective notch stress method; nominal stress method; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE

  6. 4. Micro-cracking and delaminations of composite laminates under tensile quasi-static and cyclic loading

    Author : Hiba Ben Kahla; Janis Varna; Zoubir Ayadi; Federica Daghla; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; Fatigue; damage growth; stiffness reduction; NCF; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : Aerospace industry is devoted to improving the aircraft performance while reducing its weight and limiting the emissions. Part of this objective can be accomplished with the use of high-performance long fibre reinforced polymer laminated composites. READ MORE

  7. 5. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers

    Author : Tomas Walander; Christian Berggreen; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; cohesive law; fatigue; finite element analysis; fracture energy; mixed mode; multi-axial fatigue; potential model; temperature; Mechanics of Materials; Materialmekanik;

    Abstract : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. READ MORE
