An efficient boundary element method is proposed for three-dimensional corrosion analysis of structures having net geometory, such as rebars in a reinforced concrete structure and a guard fence for a sea-side structure. The proposed method is based on the Fourier series expansion of boundary quantities, i.e., potential and current density, in the circumferential and axial directions of a net structure. It is possible for the new method to reduce largely an enormous number of elements which would be necessary in the conventional method to discretize the structures having net geometory. In order to demonstrate the usefulness of the proposed method, a couple of example problems of rebars in a concrete structure with a cathodic protection system are presented.
