Smart Sensor Networks and Integrated Systems of Structural Health Monitoring for Civil Infrastructures

摘要

Structural health monitoring (SHM), as a useful technique for ensuring the health and safety of civil infrastructures due to the damage accumulation or disaster evolvement of civil infrastructures, has more and more attract great considerations in research and engineering communities in the mainland of China since a great number of civil infrastructures are being planned and constructed each year. In this paper, the state-of-the-art and practice of structural health monitoring for civil infrastructures in the mainland of China are summarized. These contents in this paper include the development of advanced smart sensors, wireless sensors and sensor networks, data acquisition system, approach of damage detection, model updating and safety evaluation, implementations of integrated systems in practical infrastructures of long-span bridges, offshore platform structures, hydraulic engineering structures, tall buildings and large space structures in the past few years of the mainland of China. SHM systems of two cable-stayed bridges are presented in detail as examples to demonstrate the development of SHM technology in the mainland of China.
