Vehicle Collision with Bridge Piers

Journal of Bridge Engineering, 2005
Inelastic transient finite element simulations are used to investigate the demands generated during collisions between vehicles and bridge piers. Such collisions have occurred in the past, sometimes with catastrophic consequences. Two different types of trucks and two different bridge/pier systems are used in the simulations.

Experimental study on local scour at complex bridge pier under combined waves and current

, 2020
This paper presents an experimental study on scour at complex bridge piers exposed to combined waves and current. Regular waves were produced with various strength and superimposed on co-directional current with constant velocity.

Characterization of horseshoe vortex in a developing scour hole at a cylindrical bridge pier

International Journal of Sediment Research, 2019
Since local scour at bridge piers in rivers and estuaries is a major cause of bridge failure, estimation of the maximum local scour depth is of great importance to hydraulic and coastal engineers.

Experimental study of a reinforced concrete bridge pier strengthened with HPFRC jacketing

, 2020
As a consequence of material degradation, increasing traffic loads and seismic actions, a large number of existing reinforced concrete bridges are no longer safe and may represent a risk for human lives and for the robustness of the road network ...

Experimental study of the effect of submergence ratio of double submerged vanes on topography alterations and temporal evaluation of the maximum scour in a 180-degree bend with a bridge pier group

International Journal of River Basin Management, 2020
Various protective methods are incorporated in order to change the flow pattern and reduce the intensity of the vortices around the piers with the aim of reducing scour at bridge piers.

Riprap Protection at Bridge Piers

Journal of Hydraulic Engineering, 2001
Although riprap is the most commonly employed countermeasure against scouring around bridge piers, few studies exist of riprap performance under live-bed conditions.

Reconstruction of Windsor Bridge Piers

Transportation Research Record: Journal of the Transportation Research Board, 1996
The Windsor Bridge provides a two-lane highway crossing of the Susquehanna River in Broome County, New York. The structure comprises three 62.5-m (205-ft) simple-span through trusses supported by reinforced concrete abutments and solid-shaft piers. Having been built in 1935, it required rehabilitation in the early 1980s.

GRIP LENGTH FOR BRIDGE PIERS

ISH Journal of Hydraulic Engineering, 2011
ABSTRACT Proper estimation of grip length (foundation depth of pier below maximum scour level) is very important for safety of bridge piers, Lacey's recommendations are used for the design of grip length for bridges in India. Validity of Lacey's recommendation has been investigated by both experimental and analytical approaches.

Numerical Approach of Interaction between Wave and Flexible Bridge Pier with Arbitrary Cross Section Based on Boundary Element Method

, 2020
A numerical approach based on potential theory and the boundary element method (BEM) to study the interaction between surface waves and a flexible bridge pier will be developed.

Bulbous Pier: Alternative to Bridge Pier Extensions

2015
Bridge deck splashing causes deterioration to the bridge structure and renders the bridge unsafe for motorist and pedestrians. The traditional countermeasure for bridge deck splashing is pier extension, the pier extension moves the pier wave away from the bridge deck, but retrofitting existing bridges with pier extensions is costly.
