“…To identify the critical zone more accurately, in Figure 10 the stress concentration is the highest in the steel pile with the location S28 in row N3. In addition, the maximum stress occurs in the bridge foundation up to a certain height, which is consistent with the achievements of other studies that state that the damage occurs in the lower third of the steel pile [2,4,16]. In this case study, the damage occurs at a height of 150 cm from the bottom of the steel pile.…”

“…Finally, the finite element model used in future analyses, containing 121,655 elements (Figure 6). The simulation described here has been validated in a previous study by the corresponding author [4]. Thus, the low-cycle fatigue behavior of a steel pile due to annual temperature variations has been numerically investigated and the results obtained have been compared with the experimental results published by other researchers and the finite element responses of other models.…”

“…According to the results presented by scholars, and as is clear from the title of the current article, the most critical areas of integrated bridges are the middle steel piles, which are the main focus of this research [1,2,4,16,30]. Therefore, an IPE-220 steel beam was prepared according to the characteristics presented in the previous study [1].…”

“…On the other hand, bridges are classified as large structures consisting of many different components, which are assembled using various techniques such as welding, bolts, and nuts, etc. Many studies have been carried out in the field of estimating and evaluating the strength of bridges, and the most scholars believe that the joints are known as the area prone to failure due to various dynamic loads [2][3][4]. In fact, fatigue failure is one of the most challenging phenomena in various industries [5][6][7], especially transportation and construction, and bridges are no exception.…”

The first goal of the current study is to estimate the fatigue life of the middle steel piles of an integrated bridge installed in water and subject to the impact of sea waves. In the following, the authors have tried to improve the service life of this critical part of the bridge, which is also the main purpose of the study. To this end, conventional shot peening, as one of the most well-known surface treatments, was used. Axial fatigue tests were performed on samples fabricated from IPE-220 steel piles in two states without and with shot peening surface treatment. Next, the modified S-N curve was entered into the finite element software to define the effect of shot peening treatment. Different analysis, including thermal, thermal-structural coupled, and transient dynamic, were performed and various outputs were extracted for the entire structure. In all these analyses, changes in air temperature have been neglected. The most important achievement of this research is the discovery that motionless water cannot cause serious damage to steel piles. Moreover, application of conventional shot peening can increase the fatigue life of steel piles, or in other words the service life of the bridge, subjected to the impact of sea waves by about 22%.

“…They also found that the fatigue life of an IAB was predominated by the daily fatigue life, not the seasonal fatigue life because the daily temperature cycles had much larger frequency than the seasonal temperature cycles. By comparing the fatigue life from the finite element analysis (FEA) with that from the experiment, Abdollahnia et al (2021) concluded that the FEA could accurately predict the fatigue life of H-piles in the experiment.…”

Expansion and contraction of integral abutment bridges due to temperature changes force integral bridge abutments (IBAs) to move toward and away from the backfill, thus increasing horizontal earth pressures behind the abutments and inducing bending moments on pile foundations. This paper presents the state of knowledge and recent advances in understanding the behavior of IBAs in response to temperature changes including abutment movement, pile response, and horizontal earth pressure behind the abutment, examines the effect of bridge skew on the behavior, and discusses possible measures to mitigate temperature change-induced problems for IBAs. Field data show that both bending moments of piles near the bottom of abutments and axial loads of piles fluctuated with temperature. Redistribution of dead loads among bridge components due to planar temperature gradients and earth pressure changes behind the abutment contributed to axial load fluctuations in piles. Magnitude and distribution of horizontal earth pressures behind the abutment depend on factors such as abutment movement and abutment movement mode. Most of the current design methods overestimated the horizontal earth pressures at the bottom of the abutment during bridge expansion. Compressible inclusions placed behind the abutment, geosynthetic-reinforced backfill, and lightweight backfill in place of typical aggregate backfill are helpful to reduce horizontal earth pressures behind the abutment at high temperatures and temperature change-induced backfill settlements.
