Fatigue damage assessment of concrete using wide-range experimental data

This contribution focusses on the fatigue damage assessment of concrete samples using wide-range experimental data.Within this study, the concrete samples were tested under various loading conditions: static fracture, low-cycle and high cycle fatigue.This allowed us to obtain static load-CMOD, S-N curves for fatigue lifetime assessment, and mainly CMOD-N curves showing the stiffness degradation at high-cycle fatigue load regime.The low-cycle fatigue resistance is assessed from stepwise load-CMOD curves with increasing CMOD value every step, allowing to analyse damage growth between each load cycle.This study investigates the fatigue resistance of concrete samples by combining all of these experimental data and could provide useful recommendation for structural design.
