SAIL3,
Thank you for your response. I like that I am getting confirmation of my contention that the existing flange will become compact with the addition of the cover plate.
dhengr,
The existing WF is 24" wide and .4375" thick. The proposed cover plate can only be 12" wide and I have it at .75" thick. Shear is not an issue with this beam, but the maximum current moment is approximately 4100ft-kips and the propsed moment capacity will be approximately 6100ft-kips...
structSU10,
I noticed that case in Table B4.1b. That compactness check appears to disregard the existing flange. So, does that mean that the compactness criteria of the existing flange is not important once the cover plate is added?
dhengr,
Thank you for your help,
The existing WF flange is slender, 36ksi steel, while the cover plate will be a compact shape of A992 steel. This is why I am a bit unsure of how to tackle this. If the existing flange were compact then this wouldn't be an issue at all, but I am mixing shapes...
Hello,
I have a question concerning how to determine if a flange is compact or noncompact when a cover plate is attached to the flange of a currently in-service beam. I have attached a dropbox link to a sketch showing the proposed setup. My question is, do you use the whole flange width and...
