FOR, M-15 SHEAR STRESS 2.8N/MM2.

It's table 20 of IS 456.

As per my knowledge, it depends on the grade of concrete.

Please, someone explain permissible shear stress in RCC beam is 5 kg/cm^2 i.e safe in shear.
If shear stress exceeds 20 kg/cm^2 then we redesign the section.
So how you guys are saying for M15 grade concrete it is 25kg/cm^2?
If shear stress exceeds 20 kg/cm^2 then we redesign the section.
So how you guys are saying for M15 grade concrete it is 25kg/cm^2?

First of all the grade of Concrete is not mentioned in the question,
Assuming the grade of concrete to be M15 from table no 20 of IS 456, Page no 73, Maximum permissible shear stress for M15 grade is 2.5 N/mm^2 that will be 25 Kg/cm^2.

As the maximum shear stress depends on the grade of concrete we use.

How to estimate shear stress?

Please anybody clear this question how we can decide grade we take M-25 then?

It is depend only on concrete grade. How can we decide?

Then how will we guess it?
