Concrete Crushing an overview ScienceDirect Topics

2010-8-7  5.4.1 Concrete Crushing 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.

Properties of Concrete I. Compressive Strength, f’c Is the capacity of structure or material to withstand pushing forces that are axially directed. It is the maximum stress a material can sustain under crushing load. The compressive strength of concrete, f’c, is determined by testing to failure of a 28 day old 6 in. by 12 in. concrete cylinders.
