HSS cantilever beam connection
HSS cantilever beam connection
(OP)
Hello fellow engineers,
I'm trying to design a bolted moment connection between a W-shape column and an HSS cantilever beam. The HSS beam would be connected to the flange of the W-shape. While looking at some books I noticed the HSS was always a column and never a beam. Does anybody know if there's a structural reason not to use an HSS cantilever beam connected to a W-shape column?
Also, does anybody know how to check column flange for distortion due to bolts pulling on the flange?
Any help would be very much appreciated.
Thanks!

RE: HSS cantilever beam connection
As for your connection, I assume the HSS is fastened to the face as the column is continuous beyond, right? Otherwise you'd just end plate the W section and fasten to that.
Right, so if we have a continuous condition for a HSS accross the face of the column, we've got a mess. How do we ensure good restraint for the column (ie: what's going to help us keep the critical design length down), and how do we ensure a solid connection for the HSS?
I suggest the following: Use two bolts through the centre of the HSS, one through each side of the column's flange. Check the HSS for crushing loads against the snug tight condition of the bolts, and put in flanking stiffeners to the column.
