Corrosion associated with reinforcing bars is the most significant contributor to bridge deficiencies.
A review of recent National Highway System (NHS) Bridge Deficiencies data that span over the recent decade (Table 1) reveals that approximately 8.2%% of NHS bridges were classified as structurally deficient with the number consistently recorded to be above 8%% over the recent decade (Status of the Nation's Highways, Bridges, and Transit: Conditions and Performance (2010)).
The findings could stimulate wider acceptance of IRT as a rapid, systematic and cost-effective evaluation technique for critical bridge deck deficiencies, allowing to focus maintenance and repair budgets on most deserving bridge decks.
In addition, the explored SOFI analysis emerged as a practical method that can bridge the inherent deficiencies of confocal and single-molecule localization methods, especially in experiments with pronounced intraparticle differences in reactivity and low signal-to-noise ratio.
The results provided an improved understanding of the bridge dynamic behaviors and deficiencies of this bridge, and finally, led to the suggested retrofit for appropriate maintenance.
At 220-mm long, it has the advantage of bridging the bony deficiencies in the femoral canal.
The efficacy of repair jackets on post-MS resilience of repaired bridges is quantified for a prototype two-span single-column bridge bent with lap-splice deficiency at column-footing interface.
The most deteriorated bridges in Westchester tend to be small ones built more than 80 years ago, but many busy bridges have been identified as having deficiencies: The Saw Mill River Parkway bridge over the Cross County Parkway has a superstructure rated poor, meaning it has advanced deterioration.
Discrepancies between the numerical and experimental results of the bridge piers response are highlighted and deficiencies in the numerical model assumptions are discussed.
Combining external dampers and cross-ties into a hybrid system to control bridge stay cable vibrations can address deficiencies associated with these two commonly used vibration control solutions while retaining their respective merits.
