Bridge Pile Bent Number of Piles and X-Bracing System: Impact on Pushover Capacity as Scour Increases

Scour effects on the response of laterally loaded piles considering stress history of sand

“…Briaud et al [4] proposed a method to predict the scour depth around a bridge pier in clay, which was verified in the flume experiments. In contrast to the extensive research on the prediction of scour depth, very limited research [5][6][7] has been conducted to examine how to evaluate the effects of scour on piles and bridges or platform structures.…”

On the Morphodynamics of a Wide Class of Large‐Scale Meandering Rivers: Insights Gained by Coupling LES With Sediment‐Dynamics

“…A study of river morphodynamics is important from the point of view of engineering and design, as floods can cause damage to infrastructure installed in rivers. Over 30% of bridge failures in the United States are caused by scour during floods (e.g., Biezma & Schanack, 2007; Deng et al., 2015; Hughes et al., 2007; Wardhana & Hadipriono, 2003). Also, meandering river migration has contributed to the bridge and other infrastructure problems globally (e.g., Hemmelder et al., 2018; Inoue et al., 2020; Y. Yang et al., 2021).…”

Behavior of scoured bridge piers subjected to flood-induced loads

“…The behavior of scoured bridges under flood conditions involves complex interactions between bridge structures, pile foundations, soils, and water. In recent years, a number of studies [4][5][6][7][8][9][10][11] have attempted to study the behavior of scoured bridges under flood conditions. Most of these studies have been conducted based on relatively simplified models or indirect approaches.…”

“…However, the increased number of piles also adversely affects the bridge safety by inducing magnified flow-induced loads acting on the bridge. Hughes et al [8,9] evaluated the influence of scour on the performance of bridges with pile bents and investigated the effectiveness of bracing systems for mitigating the scour damage to bridges. The performances of X-braced bents with and without a horizontal bracing strut were examined.…”
