According to the FHWA National Bridge Inventory, one third of nearly 600,000 U.S. highway bridges are classified as structurally deficient or functionally obsolete. Since the majority of bridges were built using wood, steel or concrete, the same conventional materials have been used for bridge replacement or rehabilitation,...

Bridge decks’ maintenance funding requirements are influenced by bridge decks' current and predicted future conditions. Additionally, the serviceability of bridges may be negatively impacted degradation decks. inspections require considerable effort, time, cost, resources; besides, such introduce hazards safety concerns. This paper introduces a data-driven hybrid feature selection framework for...

Scour is by far the primary cause of bridge failures in the United States. Scour and other hydraulic effects are particularly threatening because the deterioration is often invisible , hidden beneath turbid water. Many scour monitoring methods attempt to measure the development of scour pockets themselves. However, this is difficult due to debris — both floating and submerged — and shifting str...

Nanjing Dashengguan Bridge, which serves as the shared corridor crossing Yangtze River for both Beijing-Shanghai high-speed railway and Shanghai-Wuhan-Chengdu railway, is the first 6-track high-speed railway bridge with the longest span throughout the world. In order to ensure safety and detect the performance deterioration during the long-time service of the bridge, a Structural Health Monitor...

Bridge inspection standards in the United States require routine visual inspections to be conducted on most bridges at a maximum interval of two years regardless bridge condition. Limitations this uniform calendar-based approach have been reported literature. Accordingly, objective study is provide new systematic for planning that integrates information from condition prediction models, data, a...

the term ‘deteriorated texture’ gives all experts as well as ordinary people almost the sameimpression. despite common points in images, the differences put iran cities in different categories based on deteriorated textures. this classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. f...
