shear strength

shear strength

(OP)
Okay, now I am going back to strength of materials days!

Let’s say that we have a 3/4 inch diameter rod. (Fy = 36 ksi, and Fu 58 ksi). AISC allows shear strength to be 0.4Fy.

My questions are:
1. What is the safety factor that the AISC uses for the allowable shear?

2. For A36 to shear, from my early college days and Mohr’s circle, steel will shear before it reaches its yield strength. Am I correct?

I would appreciate any updates on this.

RE: shear strength

For A36 rods the allowable shear is 0.17Fu for threads included and 0.22Fu for threads excluded.

RE: shear strength

Dear Lutfi,

What's the real problem? Could you explain? I think that you wanna use it for bracing, isn't it?

See You,

ERKAN

RE: shear strength

Shear yield strength is given as 1/sqrt(3)Fy which is 0.577... and is approximted by 0.6, hence 0.6 Fy.  If FS is 1.5 then allowable shear stress is 0.6/1.5=0.4Fy.  A bit late, and you probably already have the answer, lol, but better late than never right?
