    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.
