Proposed criterion for fatigue strengthening of riveted bridge girders

Most existing guidelines and recommendations for the fatigue design of riveted members are not considering the effect of stress ratio on the constant amplitude fatigue limit (CAFL). However, fatigue test data show that there is a substantial influence of the stress ratio on the CAFL. In this study, a simple fatigue design criterion for riveted members is proposed taking into account the effect of stress ratio. The applied method is based on the...
