Abstract:

The effects that stress corrosion cracking is having on the structural steel members in bridges is costing the US Government billions of dollars a year and putting hundreds of lives in danger. There are already a variety of ways to prevent stress corrosion cracking that have had some success, though are still limited. Stress corrosion cracking is the result of corrosion combined with stresses in the steel. This paper is based on structural steel S275. The solutions proposed in this paper are to reduce the corrosion rate by changing the chemical composition of the steel, and to reduce the stresses in the steel changes in the manufacturing processes have been proposed. The combination of these solutions will contribute to the reduction in the effects of stress corrosion cracking on steel S275. © 2014 University of Manchester and the authors.
