Abstract
In the periodic inspection procedure of highway bridge, inspection database for the same member and the element been accumulated at the periodic inspection of two rounds. Using the deterioration characteristics of each the member, under the conditions of a typical highway bridge, was quantitatively calculate the risk of a collapse of bridge can be reflected in the fault tree analysis.
As a result, the difference in the durability performance of each structural characteristics and member I made it clear what to actually how much influence on the probability of failure and collapse scenario. In addition, for the purpose of a reference for optimization of designing bridge structure and rational maintenance method of highway bridges, it was obtained some of the tendency and knowledge to the extent that can be carried out in practice on the significant level.
