There are some non-destructive methods for estimating a depth of reinforcing steel bars in concrete structure. In this paper, we propose a technique for estimating the depths of reinforcing steel bars through the analysis using FEM and experiments. Reinforcing steel bars are magnetized by using pulse magnetization method. The spatial distribution of magnetic flux densities BX, BY, BZ at the surface of concrete structures are measured. Two reinforcing steel bars are magnetized by using the pulse magnetic field in the same direction and the opposite direction. Magnetic flux densities BY and BZ are measured for estimating the depth of reinforcing steel bars. We have confirmed that the depth of reinforcing steel bars is estimated by using our proposed method. Furthermore, FEM analysis is performed for the experiment. The depth of the reinforcing steel bars is found to be estimated by using FEM. Relationship between the real depth by using experiments and the estimated depth by using FEM are discussed in our paper.
