- Crushing Strength Of Concrete Design .

The allowable stresses are fractions of the crushing strength of concrete (fc') and the yield strength (fy). Because of the differences in realism and reliability over the past several decades, the strength design method has displaced the older stress design method. Limit state design. It is a further step in the strength design method.
