Abstract

A bridge health monitoring system based on neural network technology is proposed in this paper. Nowadays, with the aging of the existing bridges all over the world, solutions on how to identify effectively the health conditions of bridges have become a significant issue. The method shall offer a rapid and reliable result immediately after major strikes of event without using lots of time and labor. The demand of this health monitoring system grows rapidly and researches on this topic had been discussed widely. Meanwhile, neural networks, commenced from artificial intelligence, have also shown their outstanding performance in solving complex problems. For this reason, a monitoring system using neural network was developed. Two major ground excitations recorded in Taiwan were used to establish the NARX-based system. Analytical results from different methods including transfer function, ARX-based model, and the proposed neural network-based system were used to evaluate the efficiency in health monitoring. The result shows that the proposed neural networked-based system can be used successfully with superior advantages after major earthquakes for bridge health monitoring.
