permissible limits crusing strength of concrete Concrete is strong in compression and crushing strength is determined by test Permissible bending & direct compression are as fraction of crushing strength. Ultimate Limit State: With respect to strength in shear, flexure, torsion, bond or.

The maximum Compressive Strain in concrete is taken as 0

Concrete in Flexure:Incase of Flexural members in limit state design, Steel will reach its maximum strain of (0.87fy)/Es +0.002 first.. But that doesnot mean steel will fail or fracture, since there is some reserve strength because of which it can elongate more till concrete reaches its maximum strain of 0.0035 (strain compatibility) which is known as secondary compression failure.
