Web Stiffeners
Web Stiffeners
(OP)
We have some steel where the fitted stiffeners are 5" away from where we'd like them (in a number of beams, the smallest being a W14). I have been looking through the code to find if there is a criteria for how close the stiffeners should be to the anticpated load.
The stiffeners are for web crippling, and not flange bending, so I was curious as to the allowable distance away. Obviously the force distributes throughout the web, so I wasn't sure if there was a limitation on this.
Thanks for your help!

They do not overlap at all.
Again this is only for a tensile load. Having a stiffener at less than 0.5d away from the load should still help using a 2:1 load distribution, right?

K1.3 - Local Web Yielding - Tension/Compression
K1.4 - Web Crippling - Compression
K1.5 - Sidesway Web Buckling - Compression
K1.6 - Compression Buckling of Web - Compression
K1.7 - doesn't really apply here.
So only K1.2 and K1.3 apply correct? I did miss K1.3 in my previous post.
What about having stiffeners at a distance away from the load?
Thanks.

Actually, instead of loads applied at "d" from the end, we should be looking at loads applied at "2.5k" from the end. The black HSS connections manual has an example where they use the actual length available in that direction (not to exceed 2.5k), even though the load is applied within "d" of the end.
