Concrete Bridge Deck Condition Assessment Using Robotic System Rabit
Development and implementation of RABIT (Robotics Assisted Bridge Inspection Tool) in condition assessment concrete bridge decks is described. The system uses multiple nondestructive evaluation (NDE) technologies in characterization of three most common deterioration types: rebar corrosion, delamination, and concrete degradation. The system implements four NDE technologies: electrical resistivi...
متن کاملDetection of Bridge Deck
Delamination is probably the most serious form of deterioration I which is commonly found in britlge decks. It ultimately results in large scale spalling necessitating costly repairs. This type of failure is believed to be caused chiefly from salt induced corrosion of the reinforcing steel. An instrument designed to detect delamination, and tests conducted to val:iAate its perf'ormance, are .br...
متن کاملDelamination and concrete quality assessment of concrete bridge decks using a fully autonomous RABIT platform
One of the main causes of a limited use of nondestructive evaluation (NDE) technologies in bridge deck assessment is the speed of data collection and analysis. The paper describes development and implementation of the RABIT (Robotics Assisted Bridge Inspection Tool) for data collection using multiple NDE technologies. The system is designed to characterize three most common deterioration types ...
متن کاملRapid Bridge Deck Condition Assessment Using Three- Dimensional Visualization of Impact Echo Data
Seismic/ultrasonic methods can be successfully used in condition assessment of bridge decks by evaluating changes in material characteristics and detection of development of defects and zones of deterioration. The impact echo method is of special benefit in evaluation of corrosion induced deck delamination due to its nondestructive nature and ability to detect delaminated zones at various stage...
متن کاملmodel based damage detection of concrete bridge deck using adaptive neuro-fuzzy inference system
concrete bridge deck damage detection by measurement and monitoring variables related to vibration signatures is one of the main tasks of any bridge health monitoring system (bhms). generally damage puts some detectable/discoverable signs in the parameters of bridge vibration behavior. however, differences between frequency and mode shape before and after damage are not remarkable as vibration ...
