Abstract
The world have occurred many natural disasters on a large scale in the recent years. The earthquakes without any warning have occurred frequently in natural disasters. And the bridge is not only used to transport, but also affect the relief efficiency, evacuation. Therefore, we expect the government can use this research to get repaired cost of the bridge pier rapidly in maintenances.
This research will use fragility curves to estimate repaired cost of the bridge pier, the repaired cost of the unit of bridge slab is the object of intensive study. We will create the process for this research. This research would fulfill realistic situation even more by the process. And we will establish the expectation model of repaired cost of the bridge pier. This expectation model is used to estimate repaired cost of the bridge pier by earthquakes. First, we will use fragility curves of bridges to get the failure probability of the damage state. Second, we through the expect questionnaires to get repaired cost range of the unit of bridge slab in the damage state. In the end is multiplied by the total area of the bridge slab which comply the conditions. After all, we can get the expectation of repaired cost of the bridge pier.
This research will also use New Taipei City bridge risk ranking which analyzed by risk assessment system of disasters. And added it in seventeen bridges which estimated by expectation model of the bridge pier. We can provide results to the government.
