Abstract EN
A fatigue damage assessment for concrete was carried out according to Eurocode 2.
Three frequency-domain methods, the level crossing counting (LCC) method, the range counting (RC) method, and a new proposed method, were used for the damage assessment.
The applicability of these frequency-domain methods was evaluated by comparison with the rainflow counting method in the time domain.
A preliminary numerical study was carried out to verify the applicability of the frequency-domain methods for stress processes with different bandwidths; thus, the applicability of the LCC method and the new method was preliminarily confirmed.
The fatigue strength of concrete had a minor effect on the fatigue damage assessment.
The applicability of the LCC and the new methods deteriorated for relatively low coefficients of variance of the stress process because the ultimate number of constant amplitude cycles was sensitive to the range of the cycles.
The validity of the joint probability functions of the two methods was proven using a numerical simulation.
The integration intervals of the two frequency-domain methods were varied to estimate the lower and upper bounds on the fatigue damage, which can serve as references to evaluate the accuracy of the time-domain method results.
