Additionally, based on the results of available flexural tests, crack widths at service load levels were evaluated and found to be within presently accepted limits for highway bridge structures, and were predictable using current AASHTO provisions. A parametric study investigating crack widths and patterns in reinforced concrete prisms is presented in order to establish limits to the service-load steel stress and strain. Consequently, the service-load steel strains are greater affecting cracking behavior. (Received January 29, 2013, Accepted August 16, 2013)Ībstract: A major difference between high-strength reinforcing steel and conventional steel in concrete is that the service-load steel stress is expected to be greater.
