Thanks bugbus and ThomasH for your replies.
The research papers I have access to consider the steel in elastic region as it is the main purpose of design per codes.
This case is an atypical case. There is an existing reinforced concrete pier (with a bridge deck on top) that has cracked...
Hello. ACI 224R Eq 4-2a shows a linear correlation b/w concrete crack width and reinforcing steel stress in a reinforced concrete beam (see attached). This equation is valid when the steel is in elastic region. After the steel yields, the stress-strain curve becomes nonlinear (E becomes...
