The design, fabrication, and construction of smart infrastructures is one of the ultimate challenges to engineering researchers today. Because they form the essence of system intelligence, one of the cores of smart structures technology centers around innovative sensors and sensor systems. Structural health monitoring (SHM) represents one of the primary applications for new sensor technologies. Indeed, much attention has been focused in recent years on the declining state of the aging infrastructure in Japan. These concerns apply not only to civil engineering structures, such as the nation's bridges, highways, and buildings, but also to other types of structures, such as the aging fleet of aircraft currently in use by domestic and foreign airlines. However, an important issue to smart structures is dealing with the wealth of information produced by the dense array of smart sensors ; therefore, networking and information technology become crucial areas. In this research project synergistic integration of key technologies such as modern sensors and feedback controls for design and construction of engineering systems and issues on the application and implementation to urban infrastructure systems are deeply discussed. A roadmap towards the goal is also presented.
