METHOD FOR PREDICTING REMAINING USEFUL LIFE OF EXISTING REINFORCED CONCRETE STRUCTURE

摘要

To provide a method for predicting a remaining useful life in years of an existing reinforced concrete structure capable of comprehensively evaluating the remaining useful life in years of the whole structure.SOLUTION: The method for predicting a remaining useful life in years of an existing reinforced concrete structure includes: measuring a depth of neutralization for each of a plurality of points of an existing reinforced concrete structure; determining, on the basis of the measurement result of the depth of neutralization, which of shallow neutralized points where neutralization has not proceeded to near reinforcing steel bars and deep neutralized points where neutralization has proceeded to near the reinforcing steel bars the plurality of points are; calculating a remaining useful life t1 of the shallow neutralized points and the vicinity thereof; calculating a remaining useful life t2 of the deep neutralized points and the vicinity thereof; and adopting the remaining useful lives t1, t2 calculated for the plurality of points whichever is smaller than the other as the remaining useful life in years of the existing reinforced concrete structure.SELECTED DRAWING: Figure 3
