“…Similar to the parametric analysis results, the stress range of different suspenders also increased when the road roughness changed to be Range_E. The quantitative influence on fatigue life can be evaluated through the Rain flow counting method [23,24]. The program of the Rain flow counting method was designed in MATLAB, and the counting results are presented in Figure 18 by using Suspender A and E as the example.…”

Fatigue damage of suspenders is a main concern during the life-cycle maintenance of arch bridges and suspension bridges. This paper presents a practical framework for estimating the fatigue life of suspenders under repeated traffic loads by taking a three-pylon suspension bridge as an example. First, the basic theory of vehicle–bridge interaction (VBI) is introduced and a finite element model of the bridge structure is established. Second, the fatigue load spectrum is defined in detail based on the analysis of WIM (weigh-in-motion) data. And then, parametric analysis is carried out to clarify the influence of road roughness, vehicle speed, and driving lanes. Among which, the time-dependent stress laws are simulated according to the defined fatigue load spectrum and the stress range is counted through the Rain flow counting method. At last, the fatigue life of uncorroded suspenders and naturally corroded suspenders is estimated by an S–N curve and Miner cumulative damage criterion. Results reveal that the fatigue life of suspenders is more than 100 years if no corrosion happens, while less than 20 years for short suspenders considering the influence of natural corrosion.

“…This can be attributed to the fact that failure determination due to the aging effects such as fatigue accumulation is a challenging problem to date due to the uncertainties associated with the time-varying loads. Although the studies on fatigue damage for constant and variable amplitude loading and associated crack growth mechanisms have been performed for various aeroelastic applications like suspension bridges [20], wind turbines [19], aircrafts [21], similar studies addressing the effects of structural and aerodynamic nonlinearities are limited [22,19] in hitherto literature. Sarkar et al [22] investigated the fatigue damage induced in a randomly vibrating 1-DoF aeroelastic system in the presence of fluctuating flow under dynamic stall conditions using the ONERA model.…”

“…Nowadays, it is important to study the fatigue remaining life prediction method under variable amplitude loading for the reliability in engineering (Sarkar et al, 2011). However, when the monitoring output loading of the system is variable, it is impossible to distinguish whether the monitoring output loading changes are caused by the variable input loading or early failure occurrence, the uncertainty on the loading increases the complexity of the monitoring process.…”

“…Rain-flow method is widely used for processing of variable amplitude loading (Corbetta et al, 2014;Marsh et al, 2016), and describing the variable stress (Sarkar et al, 2011), which are used to compute the average rate of fatigue damage growth. In addition, it is important to study the crack size growth based on the model parameters, and the parameters may govern the phenomenon.…”

Crack size prediction under variable amplitude loading is a very complex process, which is also important for life prediction in engineering. A crack growth model considering different stress ratio for fatigue remaining life prediction is proposed in this paper. The model utilizes stress ratio to describe the variable loading sequences, which makes the calculation greatly simplified. The rain-flow method is utilized to characterize the load sequence effects under variable amplitude loading. In addition, particle filter is utilized to estimate the model parameters describing the crack growth. Finally, case study indicates that the proposed approach is efficient in predicting crack growth and fatigue remaining life.
