Fatigue analysis and life prediction of bridges with structural health monitoring data — Part II: application

Fatigue of riveted and bolted joints made of puddle iron—An experimental approach

Numerical modelling of riveted railway bridge connections for fatigue evaluation

The assessment of the remaining fatigue life of existing, riveted railway and road bridges is gaining increased significance due to the advanced age of many of these structures. Therefore, the prob...

Development and Application of a Fatigue Class Catalogue for Riveted Bridge Components

A probabilistic fatigue assessment methodology for riveted railway bridges is presented. The methodology is applied to a typical, short-span, riveted U.K. railway bridge under historical and present day train loading. On the loading side, the problem is randomized through dynamic amplification and traffic volume; on the resistance side, the S-N curves and the cumulative damage model are treated probabilistically. Model uncertainty is represented by the ratio between actual and calculated stresses, the latter obtained through finite element analysis. Annual response spectra for a fatigue-critical connection are developed through Monte Carlo simulation, which show that there is a continual and accelerating increase in the mean stress range experienced by the connection with time. S-N curves proposed in United States and United Kingdom codes are used in combination with Miner’s rule, to estimate the remaining fatigue life of the connection for different target failure probabilities. Parametric studies reveal...

Probabilistic Fatigue Evaluation of Riveted Railway Bridges

This study was carried out with the specific objectives of providing a sensible fatigue and fracture rating plan for riveted steel highway bridges. To accomplish this objective a study of existing test data was carried out and summarized. This information was then supplemented with additional test information produced during the project using beam sections from actual riveted bridges. This permitted estimates of deterioration to be assessed and fatigue and fracture data applicable to full size members to be acquired. The goal of the riveted girder tests which examined the fatigue strength and fracture resistance of the members and assessed the toughness and metallurgical characteristics of the material was to achieve an adequate degree of understanding to permit rating recommendations to be developed.
