Description

<p>Recently, extending the service life of the bridges has come to be studied. Many bridges are built in the period of high economic growth, and they reached their service life. Consideration of rebuilding and extending the service life must be carried out.. Yokohama city conduct regular inspection of the bridges every 5 years. damage of the bridge can be assessed by regular inspection. Many bridges suffer from earthquake vibration and disturb lifesaving and the supplies transportation. Yokohama city carried out the seismic strengthening of the bridge. However, according to the periodic inspection, the damage degree of each bridge has unevenness. There is possibility that the bridge which the existing damage increase the risk for suffering from earthquake. In this study, deterioration of bearing which is subject to earthquake was predicted statistically using bridges inspection data in Yokohama city. Using the damage degree that we predicted, seismic risk was evaluated. </p>
