Artificial neural networks for non destructive testing of concrete structures

In this paper, the determination of defects in concrete structures using an ultrasound technique is discussed. A diagnostic model for concrete pillars by means of Multi Layer Perceptron neural networks is developed to locate and classify the defects. Finite Elements numerical techniques have been used to model a concrete pillar of specified size (i.e., rectangular cross section and 2 meters in ...

Non-destructive Impulse Response S’mash Method for Concrete Pile Testing

Nowadays, in the civil engineering practice, the pile-building is the most universal type of foundation. It is usually associated with bridges, fly-overs and other civil engineering objects, industrial buildings, tall buildings, chimneys, tanks etc [1]. It is essential to control the quality of concrete piles. The most accepted weight-bearing capacity measurement technique is the static probe l...

Non-Linear Non-Destructive Evaluation of Concrete

This paper explains non-linear non-destructive evaluation of concrete aimed at examining the occurrence of non-linearity under non-linear wave propagation through the concrete. Standard cubic concrete sections in damaged and undamaged conditions were investigated. The specimen was first damaged under compression testing and then subjected to non-linear ultrasonic evaluation in two directions i....
