Minimum fillet weld requirements in the AICS manual only apply to fillet welds. There is no rule or standard (as of yet) in the AISC code for penetration welds. As long as all other checks were completed, this connection is adequate. I also agree with dik, the yield line analysis for the hss...
Archie264 the connection design for this project was sub-ed out the the company I work for by the fabricator, and the EOR reviews all of the connection designs.
Haha I agree, unfortunately its the architect's vision. It's a 12 story building, and much of the structural steel is exposed, so we've been stifled before by what the architect wants.
And unfortunately I do not have access to FEA, but it would be awesome. I have it "worked" out, I went...
It is not that the tube is needed for any structural purpose, but rather an aesthetic purpose. I am not an architect, but I can tell this concept of box to wide flange has been repeated throughout this job. My issue, is that at every other location, I have not had to size the plate, it has...
Thanks for the responses!
JLNJ - I cannot visualize "splitting the tube". Unfortunately we dont have a lot of room to change section sizes at this point. I am confident that this connection will be more than adequate with a 1" plate, but it is just presenting it to the EOR with a viable...
The architect has put these things all over this job, he/she finds them aesthetically pleasing (no really a satisfactory reason, I know). So far the EOR has provided us with a plate size per the architects requests, unfortunately not for these connections.
Thank you for your response, I'll...
I am working on connecting a W10X88 Column to an HSS8x8x5/8 for a combination of shear, axial, and an applied moment. It is an architecturally exposed connection, and with that the architect would like to have a 1" butt plate. I am having a hard time proving that a 1" plate is adequate; I...
I have been working on the connection designs for a building that uses LLRS design. We also have some built up box members where we need to check the box sections for concentrated forces. I am using Chapter K as my guide for checking these columns (I did not design the box sections, just the...
Depending on how the ajoining members are coming together. In this case, having to do a weld all around, the maximum fillet weld size would be equal to the thickness of the adjoining member-1/16" per AISC a-36 (13th edition), with 1/4" minimum weld. If you are just developing the weld for a...
