Abstract
The calculation of LCC will be the important subject in the establishment of BMS. The LCC includes the initial construction cost, the maintenance cost, the exchange and rehabilitation cost and UC. These costs are sometimes shown concretely, but UC has been shown only the word. However, in the relation of the road network around the bridge, it is anticipated that UC becomes large. For UC, the evaluation of the increase by the detour traffic in running time, the economy evaluation, and the social evaluation are included And here, only the time increase due to detour traffic is evaluated In this paper, the numerical example of LCC of RC bridge based on seismic performance design method shows the importance of UC in the decision making of the design and the bridge management strategy.
