What does 'G' stand for in steel structural Properties?

AIR-AUSSIE · 26-08-2009, 17:18

The title says it all. Can't remember what G stands for in structural steel properties and need to calculate it. I've googled it but couldnt find what I was looking for. Don't have any notes to hand.

Cheers for the help.

G = Shear Modulus

If this is correct how would I calculate its value for an I beam.

G = E / 2(1+v)

v = poissons ratio

v (for steel) = 0.25 - 0.3.

is this correct?

Off the top of my head, that looks right, but I'll check it out for you in a while and confirm it.

Yup that is right, G is the shear modulus!!!
