Simulation of non-destructive testing methods of ultrasound in concrete columns

Abstract:

Among the processes that are conducted to perform the inspection of the internal reinforcement of concrete structures, to study the component it is destroyed directly, in most cases some partial and total. By means of a sustained theoretical approach, several objectives were established to evaluate through modeling and simulation methods that could be useful for non-destructive testing in structural concrete columns. Given these variables (positions and diameters of reinforcements) were established mathematical models of the physical principles that constitute the operation of the respective non-destructive testing methods and computational models were made of reinforced concrete column, finally the data were interpreted from simulations into a graphic reconstructions which representing an approximation to the column being analyzed. The result was a conceptual design which was the product of the information gleaned from the simulations of the two methods worked, longitudinal transmission and pulse echo, corresponding to the ultrasonic non-destructive testing. This research describes theoretically non-destructive testing methods based on ultrasound, which can be used to build devices that claim to prevent partial or total destruction of the structure to be studied, and imaging techniques that are useful to identify the reinforcement positions of the concrete column based on the collected data from the simulations. © 2013 by ESG.
