Collars for Scour Reduction Around Different Shapes of Bridge Piers

Collars play an effective role in reducing scour by preventing direct collisions of the flow with the piers. Furthermore, because most rivers meander, this study considered various shapes of

Skew Bridge Analysis With Various Skew Angles

Today''s bridge decking frequently exhibit some skew, taper, or curvature. It is preferable to have straight carriageways than to tackle horizontal bends for large contemporary vehicles and high traffic.

High transmission in 120-degree sharp bends of inversion

In this study, to identify the origin of high transmission in 120-degree bent PhCWGs, we separate the effect of inversion symmetry and the domain-wall configuration by employing a specific...

Bend, the remnants of a community 2.1 miles (3.4 km) northwest of Dome Creek in central British Columbia, comprises several scattered rural properties stretching

Effect of the Shape and Position of the Bridge Pier on the

The presented brief review of the earlier works suggests that the shape of the bridge pier section and its position in the bend are two important parameters affecting the pier scouring. In this

Effect of the Shape and Position of the Bridge Pier on the

Also, the results showed that the maximum scour depth is equal to 4.22 times the pier width in the case of rectangular pier located at 90-degree bend position and the lowest scour is equal to 2.12 times the

Numerical Study of Bed Topography Variations Owing to Placement of

In this paper, the scouring around a triad series of vertical bridge piers located in a bend is investigated using SSIIM software. To this end, some of the most essential parameters such as the

Length of ELEVATION should match the length along the layout line at centerline of bent (NOTE: For skewed structures, the skewed length is longer than the width of the bridge normal to the bridge

Bridge Inspection: Piers and Bents (BIRM)

The footing transmits the weight of piers or bents, and the bridge reactions to the supporting soil or rock. The footing also provides stability to the pier or bent against overturning and sliding forces.

Experimental investigation of flow pattern at 180° bend

The generation of vortices in sharp bends of rivers is a well-known phenomenon. However, their influence on the bridge pier has not been investigated deeply. This study studies the

High transmission in 120-degree sharp bends of inversion

The study explores high transmission in 120-degree bends of photonic crystal waveguides. It reveals that high bend-transmission is primarily influenced by domain-wall

Bridge Inspection: Piers and Bents (BIRM)

A pier or bent is an intermediate substructure unit located between the ends of a bridge. Its function is to support the bridge at intermediate intervals with minimal obstruction to the flow of traffic or water

Effect of the Shape and Position of the Bridge Pier on the Bed

This paper has experimentally investigated the simultaneous effect of the pier shape and position on scouring in a sharp 180-degree bend. Several experiments were performed on the bend
