The number of bridges in operation has increased. Along with the increase length time are service, structural safety also decreases. Bridge substructure is a key component bridges, but there few studies on management and identification water bridge damage. Deep learning focus research field target detection, this document lightens YOLO-v4 to achieve precise intelligent determination concrete cr...

High costs for the repair of concrete structures can be prevented if damage at an early stage degradation is detected and precautionary maintenance measures are applied. To this end, we use numerical wave propagation simulations to identify simulated in using convolutional neural networks. Damage subjected compression modeled mesoscale discrete element method. Ultrasonic simulation on damaged s...
