Ship-Bridge-Pier Protective Systems
This paper describes the analytical and experimental studies on the behaviors of a ship subjected to a sheering flow induced around a rectangular solid-type marine structure, and also deals with ship-structure protective systems against ship impacts. Large bridge piers, which are constructed in a narrow waterway with strong tidal currents, are treated ...

We synthesize and characterize a series of well‐defined anilido–imine Fe(II) alkyl complexes that demonstrate high activity and selectivity in the cyclohydroamination of unprotected primary amines tethered to unactivated alkenes. By tuning the steric and electronic parameters of the anilido–imine ligand, we develop a catalyst that outperforms ...

ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Mechanical Analysis of Junction Pier of Fuzhou-Xiamen High-Speed Railway Rigid-Frame Bridge
The continuous rigid structure bridge on both sides of the Quanzhou Bay Crossing Bridge uses double-limbed thin-walled flexible piers for the junction piers between the links, and the whole bridge has no bearings.

ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Reliability Analysis of the Main Pier during the Construction Period of HLCR Bridges
In the process of cradle construction for high-pier, long-span, continuous, rigid-frame (HLCR) bridges, the strength failure and instability damage of the main pier will directly affect the bridge construction safety.

Effect of Bridge Pier Shape on Depth of Scour
Scour at bridge piers is a common problem in infrastructure engineering, as local scour around bridge piers is one of the most common causes of bridge failure. Prediction of the maximum depth of local scour thus plays an important role in ensuring safety

ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

A bridge pier integrated by multiple steel pipes with directly-connected piles was proposed as a way to design a rational foundation for bridge pier structures, and its feasibility was examined by comparing its seismic behaviour with that of a bridge ...
