Shear Stress Checking

[Mateus_R]

Hello everyone,

Following the discussion: Link, if I would like to evaluate the shear stress at the base of the plate,
what safety factor should I select to compute the allowable shear stress?

The AISC 360-16, G.1 (Design of Members for Shear) , recommends Yield Strength / 1.67 (Equivalent to Yield Strength * 0.6)

The AISC 360-16, F.4 (Allowable Shear Stress - Beams and Other Flexural Members), recommends Yield Strength * 0.4.

I'm a little bit confused due to the description of chapters.

Thank you for your help.

Well dont mix up allowable and design stress

Ok, but can I consider the 0.4 factor for allowable shear stress (suggested for beams), if I consider a plate, as mentioned in the link?
