Idealized Stress Strain Curve of Concrete | Why 0.67 times fck | IS 456-2000

This video explains what is idealized stress strain curve of concrete in rcc design and why we take 0.67 times of fck value of concrete.

There are 3 curves in the graph
1) Idealized curve for concrete (Cube)
2) Idealized curve for concrete (Structure)
3) Design Curve.

It is very essential to reduce the characteristic value of concrete when you actually design the rcc element and why it should be reduced is explained in this video, kindly watch complete video to know the reason behind it.
