In late years a structure built for the rapid economic growth period greeted update time all at once, and it was with a problem, and there was particularly much corrosion of the steel type I figure in a figure end, and what the maintenance that was enough for all structures was not careful to occurred and examined the reinforcement method by the thing with the patch being mainstream, and simulating the trass reinforcement for the corrosion figure using three dimensions FEM analysis in this study whether the figure with the corrosion loss could get the proof stress that was equal to a fitness figure.
