Allowable stress/Permissible stress:

Axial stress in tension and compression = 0.60fy.
Bending stress in tension and compression = 0.66fy.
Maximum Permissible Bearing stress (at supports)or bending stress in column base = 0.75fy,
Maximum Permissible average shear stress = 0.40fy,
Maximum shear stress = 0.45fy.

Allowable stress:

In axial tension =0.6fy.
flexure = 0.66fy.
shear = 0.4 - 0.45fy.

It should be 0.6fy. I too agree.

Naveen said:   7 years ago
Why taking of that 0.6?

Raj said:   7 years ago
Yes, here it is 0.6fy.

Anomiii said:   7 years ago
It is 0.6fy.

For mild steel fy= 250 N/mm^2.

& we generally use mild steel.

Why 250N/mm2? @Jayasrisiva.

Allowable stress in axial compression.

= 0.60 * yield stress.

= 0.60 * 250 N/mm2.

= 150 N/mm2 or 1500 kg/cm2.
