Flange Buckling, Shear
Flange Buckling, Shear
(OP)
I have a temp structure where my 4 post carry 186 kips each and being supported by a w14x120x25' beam. Under the each post is a 2'x2'x3/4" base plate. I am worried about shear and flange buckling, is this a concern? How do I approach this checking?






RE: Flange Buckling, Shear
Please clarify the question, 744 kips is a serious amount of load!
Is each post supported by one beam? Are the base plates are between the posts and the beams, or are they beam bearing plates? What shape are the columns? What is their orientation with respect to the beam flange? Even though we have high-speed internet, I can't read your mind...

It also seems that a 14" deep beam spanning 25 ft seems a little shallow, so check deflections. You should probaby make sure that you're comfortable with your assumptions about top (compression) flange lateral support points, at extremities, and at the point loads.
But if I could suggest only 1 thing, I would have this work checked by a more experienced colleague, not by some internet kook like myself. Again, you don't really know that I'm not some structural engineer wannabe hacker dispensing advice...
On my use of the word kook, please disregard. I've been playing with the baby a few too many hours today...
