Enhancement of riveted steel bridges by adding a trough in UHPFRC acting in composite action

Eugen Brühwiler

Riveted railway bridges are commonly considered as being “old”, having fatigue damage and are therefore replaced. While this practice should be by now obsolete by using novel engineering methods like structural monitoring, prolongation of the service durat ...

Measurement and prediction of the transformation strain that controls ductility and toughness in advanced steels

Helena Van Swygenhoven, William Curtin, Francesco Maresca, Efthymios Polatidis

New-generation multi-phase martensitic steels derive their high strength from the body-centered cubic (BCC) phase and high toughness from transformation of the metastable face-centered cubic (FCC) austenite that transforms into martensite upon loading. In ...
