| 抄録: | Prestressed concrete (PC) bridges account for about 44% of all bridges in Japan, and damage of PC tendons caused by defective grouting has been reported. In order to inspect, repair and maintain the PC bridge efficiently, it is necessary to develop a monitoring technology that can quantitatively and simply evaluate the integrity. This study examines changes in bridge performance and modal parameters of PC box girders due to progressive loading, and defective grouting and failures in PC tendons through the experiment. Static loading test showed that local cracks were dominated around the location of defective grouting and failure of PC tendons. A moderate correlation was observed between the energy-based bending performance and the natural frequency of 1st and 2nd bending modes |
