Abstract

Recently, the inspection of position and depth of reinforcing steel bar in a reinforced concrete structure is important. An electromagnetic induction method and an electromagnetic radiation radar method are used for inspection techniques of nondestructive. But, a general inspection technique also has the problem. Other techniques are actively researched now. Authors previously proposed a method of estimating position, depth and diameter of a single reinforcing steel bar by using the pulse-magnetization. In most cases reinforcing steel bars are usually found in more than one the reinforcing steel bars. Authors examined the method estimating the positions of reinforcing steel bars in more than one the reinforcing steel bars. The magnetization characteristic of the reinforcing steel bar was examined, Authors confirmed about the technique for estimating of the position of the reinforcing steel bar through the basic experiments and simulations, and report.
