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.

Side objectives:

- 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.

Program:

- Introduction into fatigue and fracture

- Fatigue of parent metal and cables

- Fatigue of welded joints

- Fatigue of bolted and riveted joints

- Orthotropic bridge decks

- Fluctuating loads on bridges

- Determination of stresses

- Fracture mechanics

- Practical examples
