In recent years, monitoring technology has been attracting attention in the field of civil engineering structures. We are studying the application of various monitoring technologies to the PC box girder bridge in operation for the purpose of detecting Function degradation and alerting when the load capacity is reduced. This paper shows examples of measured data of static / dynamic strain measurement, vibration measurement, and live load measurement (structural stiffness monitoring). We also described the characteristics of each measurement and the prospects for future monitoring technology.
