Fatigue of Steel Bridges - 1st edition
Venue: Hotel Holiday Inn, Lisbon
Organizer: CMM - Associação Portuguesa de Construção Metálica e Mista
Main objective: providing the knowledge and tools required to design a bridge structure so that it has an adequate fatigue life.
- Phenomenon of fatigue: Obtain knowledge on the basics of fatigue and fracture of (welded, bolted and riveted) joints, including the aspects that are relevant and that are less relevant.
- Designing for fatigue: basics of calculation using S-N curves, background of S-N curves, scatter in fatigue strength, importance of execution quality.
- Fatigue loads in bridges: measurements of road traffic, measurements of rail traffic, determining which load effects are important, relationship with fatigue load models in standards.
- Stress definition: when to use nominal stress, geometric stress and effective notch stress. How to extract the correct stresses from the finite element method.
- Fatigue of orthotropic bridge decks: issues, remedies, repair and strengthening methods.
- Remaining life after inspection: how to determine the remaining life and inspection intervals using fracture mechanics.
