Application of Intelligent Materials to Health Monitoring for Civil Engineering

As the large scale and more complicated civil engineering is developing rapidly, it is becoming a more important task to realize the real-time, on-line health monitoring for civil engineering. The intelligent materials have a bright and broad prospect of application in these fields for their unique advantages. From the viewpoint of health monitoring for civil engineering, the mechanism and features of four kinds of intelligent materials, i.e. optical fiber, shape memory alloy, piezoelectric material and carbon fiber reinforced concrete are described in this paper, as well as their status of domestic and foreign researches and applications. The research prospect and development direction are discussed either.
