It consumes more concrete

It undergoes high strain

It fails sudden

Appearance is not good

Depth of neutral axis is less than limiting depth of neutral axis

Moment of resistance is less than limiting moment of resistance

Tensile strain in steel reaches at yield value while maximum compressive strain in concrete is less than its ultimate crushing strain

All of above

Undergo larger deflection at failure

Fails sudden

Capable to carry stress reversal

Less stiffer
