Abstract: For small bridges managed by municipalities, in order to apply to a large number of bridges than precision, we construct the structural performance simple assessment system that emphasis is placed on simplicity. This system can evaluate the structural performance of bridges in a certain area by obtaining deterioration data from the representative bridge by non-destructive testing. This system does not require a lot of cost and time, because of the less amount workload of survey and analysis. As the structural performance, we evaluate load-bearing performance from the incubation period to the deteriorated period based on structural performance and deterioration factors. However structural performance and deterioration progression have uncertainly factors. Therefore we apply probability method to the system. Since the system of this research is a simple and doesn't require a lot of cost and time, it is possible to periodically update the assessment results. Therefore, we propose efficient maintenance method using this method, such as utilization of area maintenance method.
