Abstract: Recently, bridge collapse accidents have become increasingly frequent during the flooding season, and foundation scour is one of the main reasons. Tracking scour evolution accurately is a key premise for preventing and ...

Abstract: The traditional design method, with overall factors of safety, is still employed in Chinese specifications for gravity-type anchorages (GTAs) in suspension bridges. In this work, we investigated the safety-margin design ...

Abstract: Flooding occurrences have become increasingly severe, posing a serious danger to end-user safety and bridge resilience. As flood fragility assessment is a valuable tool for promoting the resilience of bridges to climate ...

Abstract: A CFD-based simulation methodology for bridge scour using an Eulerian two-phase flow model is proposed in the present study. The basic conservation equations and four unique simulation issues are firstly addressed during ...

Abstract: A computational fluid dynamics (CFD)-based simulation methodology using a dynamic mesh updating technique is proposed in this study. This method can numerically describe the complicated 3D scour behavior around the piers ...

Abstract: While the suspended sediment loads play a very important role during the process of bridge-scour development, no computational models exist for reliable quantitative simulation and analysis of such loads during the scouring ...

Abstract: Overturning collapse has been regarded as one of the most critical failure modes for single-column-pier bridges in current practices. To reveal the entire overturning process, a meticulous three-dimensional (3D) simulation ...

Abstract: A bridge scour identification method was developed based on a time-frequency analysis that was combined with trend change detection. The basic concept behind this method is to probabilistically consider the interference-induced ...
