Structural Health Monitoring

The process of nondestructive evaluation (NDE) or structural health monitoring (SHM) uses a series of new and existing technologies that are designed to monitor various internal and external conditions of civil engineering infrastructure, such as bridges. This article discusses the technological aspects of SHM, describes some companies involved in providing SHM services, and reviews research efforts focused on monitoring and improving the structural health of the nation's bridges. Some of the technologies involved in SHM are fiber optics, wireless communications, ground-penetrating radar imaging, and information technology. Using technology, owners and engineers are able to predict more accurately the longevity of existing structures as well as design more durable, smarter structures. SHM systems can be engineered to monitor humidity, temperature, chloride ingress, corrosion potential, vibration and strains. There are also systems for monitoring structural steel on bridges, as well as the cable systems for suspension bridges. Since 1998, the Federal Highway Administration's NDE Validation Center has provided state highway agencies with independent evaluation and validation of NDE technologies, offered technical assistance and developed new NDE technologies.
