  1. 6. Fatigue of steel bridges : New structural details and the implementation of high strength steel

    Författare :Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 8. Composite Action and Confinement Effects in Tubular Steel-Concrete Columns

    Författare :Mathias Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; connection; composite action; composite column; finite element analysis; bond; confined concrete; high-strength concrete; experiment; concrete-filled steel tube;

    Sammanfattning : Composite columns composed of concrete-filled steel tubes (CFT) have become increasingly popular in structural applications around the world. This type of column can offer many advantages, for instance, high strength, ductility, and large energy absorption capacity, as well as increased speed of construction, positive safety aspects, and possible use of simple standardized connections.
