MICROTREMOR MONITORING OF THE BRIDGE PIERS UNDER DISTURBANCE

Experimental Investigation of Seismically Resistant Bridge Piers under Blast Loading

This paper reports the findings of research examining the blast resistance of bridge piers that are designed in accordance with current knowledge and specifications to ensure ductile seismic performance. Blast testing was conducted on 1/4 scale ductile RC columns, and nonductile RC columns retrofitted with steel jacketing. The seismically designed RC and steel jacketed RC columns did not exhibi...

Vulnerability Reduction for Bridge Piers

Estimating piping around bridge piers using the SSIIM software

Estimating maximum scour depth is normally required in order to determine the depth of  bridge piles. The present paper uses the SSIIM Software which considers flow and sediment equations in a three dimensional manner. The software models flow field around circular bridge pile by resolving Navier-Stokes three-dimensional equations and k-  method, and by temporary solution of flow field and cont...

Evaluation of the Extent of Backwater Effects of Bridge Piers

Introduction... The construction or renovation of bridges may require placement of bridge piers in the channel or floodplain of natural waterways. These piers will obstruct the flow and cause an increase in water levels upstream of the bridge for subcritical flows. The increase in the water level is called the backwater. The amount of backwater caused by piers depends mainly on their geometric ...

In-situ Wireless Monitoring of Fiber Reinforced Cementitious Composite Bridge Piers

High-performance fiber reinforced cementitious composites (HPFRCC) are a cement-based material in which a relatively low volume fraction of short fibers (steel, polymeric or carbon) are included in a cement matrix to produce a material that strain hardens under tension. Exhibiting high damage tolerance and tensile strain capacity on the order of 1 to 3%, HPFRCC materials can be used to reduce t...
