Mean Flow Structure and Local Scour around Single and Two-Column Bridge Piers [PDF]
علوم و مهندسی آبیاری, 2019 Bridges constructed across rivers are among the most important structures, especially during and after flood events. Bridge piers are exposed to some hazardous factors such as local and contraction scour hydrodynamics.

Effect of debris accumulation on scour evolution at bridge pier in bank proximity
, 2021 Large debris transported by flood affects scour features at bridge piers and increases the risks of structural failure. Geometric characteristics of the debris and the relative position of the pier with respect to the river bank are important parameters ...

Log Jams at a Bridge with a Pier and a Bridge without Pier
Procedia Engineering, 2015 AbstractA flume experiment was carried out in a rectangular flume in order to investigate interaction between two different model bridges and logs from the viewpoint of flood disaster prevention. Logs is assumed representative of flowing wood during floods. The model bridge with a pier and model bridge without pier were used as an obstruction in rivers.

A Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges [PDF]
Civil Engineering Infrastructures Journal, 2018 Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic ...
