Behavior of reinforcing steel and reinforced concrete undergoing stray current
, 2021 Currents flowing along paths not being elements of a purpose-built electric circuit, are called stray currents. Various types of reinforced concrete structures (such as viaducts, bridges and tunnels) in the neighborhoods of railways may be subjected to ...
