There are approximately 730,000 bridges in Japan, of which 59% will be 50 years old by FY2032. For safe use of aging bridges, monitoring is required at all times. Therefore, we are carrying out damage evaluation of fixed beams at both ends as a fundamental study to apply the measurement method combining SAW devices and geophones to bridge health monitoring. In this study, we report the results of the evaluation using a convolutional neural network with a 1D image of the time response.
