Response spectrum method for fatigue damage assessment …
To further illustrate the accuracy of the RSM for fatigue damage assessment, especially for the RSM-SRSS and RSM-MRS, the Single Moment method is used as a benchmark to calculate the relative errors of expected damage rate and expected fatigue life at each node, as shown in Fig. 6 and Fig. 7. The relative errors of the RSM-CQC are almost equal ...

Relative damage evaluation of concrete in a road bridge by AE rate
For effective maintenance of concrete structures, it is necessary to evaluate quantitatively not only the strength of concrete but also the degree of damage. Quantitative damage evaluation of structural concrete is proposed by applying acoustic emission (AE) technique and damage mechanics.

A non-negligible relative damage rate of about 18.5% is observed at the trailing edge—hub transition. A summary of the damage rate results is provided in Table 41.11. The deviations of the damage rate with respect to the fine grid solution reach from about −17% to + 22% and are therefore considerable compared to the variance of the CFD ...

Determination of relative damage of asphalt pavement from reduced tire
Based on linear relative damage analysis, in average, real tires with tread are 2.6 times more damaging. Furthermore, nonlinear relative damage analyses indicate that real tires with tread induce about three times more rutting compared to the worn-out control tread.
