Visual inspection and bridge management
… inspection prior to its implementation in a Bridge Management System (BMS) using Value of Information (VoI). Visual inspection is the principal assessment method for bridge structures, whereby a condition rating is assigned reflecting the structural condition of a bridge, based on the …

Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems
… prone to the inland and coastal floods. Bridge structures are under the constant threat of these natural disasters. Superstructures can be washed away due to lateral forces generated by floodwater. Floodwater can also accelerate scouring around bridge piers, which often contributes to …

Effects of disparate information levels on bridge management and safety
… planning and life-cycle assessment methods for bridge networks have received large research interest for many years; with modern emphasis often based on probabilistic approaches, due to their ability to handle uncertainty. This allows for risk-based approaches to quantify structural safety, …

Improvement of the approaches to monitoring of reinforced concrete bridges subjected to chloride-induced reinforcement corrosion in bridge management systems
… corrosion in reinforced concrete (RC) bridges has undeniably become the main cause of civil infrastructure durability problems in many countries. The steel reinforcing in concrete corrode when certain conditions (e.g., carbonation, chlorides, insufficient cover and moisture) are met. …

Developing Condition-Based Triggers for Bridge Deck Maintenance and Rehabilitation Treatments
The bridges in the U.S. highway system suffer from deficiencies in both their structural condition and functionality. In an effort to improve the condition of bridges, highway agencies continually seek effective and efficient approaches to maintenance and rehabilitation (M&R) treatments for their …

An investigation of the relationships between inventory and inspection data of RC bridges and RC culverts in the Western Cape Province
Bridges and Culverts form critical links within transportation networks. They are costly long term infrastructure investments and are essential to a country’s economic functioning and society’s everyday lives. They are prone to deterioration due to unfavourable chemical, mechanical and physical …

Evaluation of Policies for the Maintenance of Bridges Using Discrete Event Simulation
With the recent developments of several bridge managements systems and their wide-spread use, bridge engineers are realizing the importance of systematic and well planned investments and appropriate management. However the results are far from satisfactory. Bridge management systems need more …

Data Driven Bridge Deck Deterioration Modeling and Maintenance Intervention Scheduling
<p>Majority of over 617,000 bridges across the United States are significantly impacted by environmental factors, aging materials, and heavy traffic loads. According to the 2021 Infrastructure Report, nearly 231,000 bridges require repair or preservation work, with 46,154 (7.5%) being classified as …

Corrosion rates and the time to cracking of chloride contaminated reinforced concrete bridge components
In order to predict the future needs of existing bridges, Bridge Management Systems use models to predict the time when damage will reach a level to cause repair, rehabilitation, or replacement of the structure. One such model is the deterioration model, which has three distinct phases. The second …

Condition Analysis of Concrete Bridge Decks in Utah
Concrete bridge decks in Utah are experiencing observable deterioration due primarily to freeze-thaw cycles and the routine application of deicing salts during winter maintenance activities. Given the need for increasingly cost-effective strategies for bridge deck maintenance, rehabilitation, and …
