Bearing stiffeners on crane-runway beams 2

[GalileoG]

Hello all!

I am designing a crane runway beam and it seems like I will need bearing stiffeners to prevent web crippling/yielding. My question would be, how would I space these bearing stiffeners? The crane of course moves through the length of the beam, making web crippling/yielding a problem throughout the length. Would I have to choose a beam with a thicker web as opposed to using bearing stiffeners? If not, I ask again, how do I determine a suitable spacing for these stiffeners? Thanks!

So you were, I should have read it properly.
