Cathodic protection (CP) systems for atmospherically exposed reinforced concrete structures are presently designed using empirical formulas developed during laboratory research and initial field installations. This paper discusses the use of mathematical modeling to predict the distribution of current by a CP system so that optimal current distribution can be appropriately considered in the design. Such modeling would also provide important design information for developing CP systems for prestressed concrete structures where control of current distribution is critical in avoiding hydrogen embrittlement.
