An Initial Investigation on the Potential Applicability of Ultrasonic Testing to Assess Effects of Corrosion on Linear and Nonlinear Elastic Behaviour of Pre-stressing Steel Strands

Popis výsledku v původním jazyce

Corrosion of pre-stressing strands causes a deterioration of condition of civil engineering structures like bridges, therefore periodic inspections are necessary to prevent collapse of such structures. The corrosion of steel is a slow process however it can be well reproduced in the lab using accelerated corrosion process. Monitoring the amount of corrosion in a sample is of great importance to predict the integrity and the residual life-time of structures. The ultrasonic techniques were proposed as valid methods of analysing the data recorded during the monitoring. In this paper we show results of our experimental study and the application potential of ultrasonic techniques to analyse the effect of damage induced by accelerated corrosion on the linear and nonlinear elastic behaviour of a steel strands. These initial results show the possibility for the application of nonlinear ultrasonic testing methods for monitoring of condition of strands which are built into bridge girders.
