Fundamental principles of the reinforced concrete

The Mw 8.8 earthquake in 2010 in Chile provided valuable information regarding the damage and potential design code changes for reinforced concrete (RC) structures. Many modern RC buildings suffered severe damage, mainly in the form of concrete cover spalling, followed by longitudinal boundary bar buckling and concrete crushing.

Concrete Crushing - an overview | ScienceDirect Topics

Concrete crushing after yielding of steel reinforcement represents an under-reinforced member, which is typical of current reinforced concrete design standards. This failure mode ensures that a high level of member ductility is maintained prior to failure, thus providing ample warning before collapse.
