Fatigue Damage Factor Calibration for Long-Span Cable-Stayed Bridge Decks

Alain Nussbaumer, Cláudio Alexandre Pereira Baptista, José Joaquim Costa Branco de Oliveira Pedro

Part 2 of the Eurocode 3 (EN 1993-2) proposes a straight forward fatigue verification method using a single heavy vehicle model (FLM3) and a damage equivalent factor, lambda, to represent the fatigue damaging effects of the real traffic on road bridges. Th ...

Probabilistic S-N curves for constant and variable amplitude

Alain Nussbaumer, Cláudio Alexandre Pereira Baptista, António José Luís dos Reis

Welded details in steel bridges are subjected to fatigue lives up to 200.10(6) cycles due to traffic loads. While the majority of these stress ranges are below the Constant Amplitude Fatigue Limit (CAFL), some few high stress cycles can trigger the start o ...

Fatigue behaviour of CHS tubular bracings in steel bridges

Alain Nussbaumer, Saad Kannuna, Cláudio Alexandre Pereira Baptista, José Joaquim Costa Branco de Oliveira Pedro

The structural solution for cross girder bracings or box girder diaphragms in steel bridges is often made with tubular elements, specially efficient if compression is required for structural behaviour. The connection between the tubular elements and the gi ...

Multiaxial and variable amplitude fatigue in steel bridges

Cláudio Alexandre Pereira Baptista

Modern bridge construction all over Europe in the last decades, has highlighted the importance of steel solutions for the design of bridges. Steel bridges have become slender and lighter with the generalisation of welded connections. These features increas ...

Traffic load generation for the fatigue assessment of the 3rd Bosphorus bridge

Alain Nussbaumer, Cláudio Alexandre Pereira Baptista

This report presents the traffic simulation model for the fatigue life prediction of the stiffening cables and hangers from the 3rd Bosporus bridge in Istanbul, a 2164m long hybrid suspended/stay-cable bridge with a main span of 1408m. Probabilistic models ...

Fatigue behaviour and detailing of slotted tubular connection

Alain Nussbaumer, Luís Costa Borges, Cláudio Alexandre Pereira Baptista, Santosh Yadav

Tubular elements are used in steel structures not only for bracing of other members but also as cross girders diaphragms. They are a competitive solution both due to the lightweight and structural efficiency. Slotted tube-to-plate connections are the natur ...
