Dynamic Adaptability of Spherical Bearings in Small-Span Bridges for Heavy-Haul Railways

Buildings
Plate bearings in existing small-span bridges for heavy-haul railways have exhibited corrosion, detachment, and surface cracks under large axle loads, making them inadequate for the “capacity expansion and renovation” of heavy-haul railways.

LOCAL SCOUR AND BED EVOLUTION AROUND A SUBMERGED CYLINDRICAL PIER

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2007
Laboratory experiments were conducted on local scour and bed evolution around a cylindrical pier. Not only with a traditional non-submerged pier, but some cases with a submerged pier were explored. Experiments were carried out in both static and dynamic scouring conditions.

Investigation of the Effect of Cable on the Control of Scour around the Piles Group in the River

علوم آب و خاک, 2019
In this study, some experiments were carried out in a rectangular plexiglass flume to study the effect of the cable around a vertical tripod and two piles groups with different angles. In this research, a series of experiments were performed by placing a

The Application of Numerical Method and SKM Quasi-Two-Dimensional Model to Estimate the Shear Stress around a Cylindrical Pier with Submerged Vanes [PDF]

مهندسی منابع آب, 2019
Investigation of the shear stress to estimate the scour hole around bridge piers is of utmost importance, but a review of the literature shows that the study of this factor, around protected piers by various methods of scour control has not been studied ...

Experimental Study on Improving the Strength and Ductility of Prefabricated Concrete Bridge Piers Using GFRP Tube Confinement

Buildings
The application of precast assembled pier systems in high-seismicity regions is often constrained by their seismic performance limitations. To validate the optimization effect of GFRP confinement on the hysteretic performance of bridge piers, this study ...

A Sensitivity Analysis of Ship–Bridge Spacing under the Coupling Effect of Turbulence and Ship Motion

Journal of Marine Science and Engineering
The hydrodynamics of the flow around piers affects the motion of ships navigating near these structures, while the motion of the ships, in turn, affects the distribution of the flow field near the piers.
