Hokie66 - although it is my job to provide delegated design, a lot of problems on projects could be resolved if the EOR were to do their own connection designs in the first place. Doesn't hurt my feelings at all. I'm good with sticking to simple shear connections designed per fabricator specs...
Here is the layout of the steel. I think I might need to contact the EOR again to verify the direction of the loads.

The shear is confirmed to be vertical, but I have not questioned the loads as this particular EOR is troublesome and has pushed everything off to me. I questioned the loads on some rod bracing saying the rod size was under-designed and their comment in return was that the design was to be by the...
I am a delegated connection design engineer working on some connections on a wind screen on the top of a building with some high shear loads. My current issue is designing a shear connection for an HSS6x6x1/4 beam to an HSS18.000x0.500 column. The highest given shear load is 76 kips...
JoshPlumSE - thank you so much for your informative response. I too worked in the industrial field for a number of years before working with steel fabricators so I appreciate your perspective. I will review the resources you have mentioned and see if there is anything I'm missing. I think it...
I do have a subscription to that magazine. Thank you for suggesting that. It's not that I'm totally ignorant about building design in general. I just don't know the rules of thumb (where to put bracing and how often you need braced bays, when to use composite floors vs non-composite, spacing...
I would like to know if there are any design classes or good books to read to get more familiar with the intricacies of building design. I am a licensed structural engineer, but my professional career has not lead me into building design. I work at a small firm assisting steel fabricators, but...
I am designing a stair system in a building where the intermediate landings are being supported off the overhead steel structure at 3 of the 4 corners. Right now, the detailer shows one of the back corners supported off a seat on a structural column, but is using hanger rods for the other three...
It seems like I can get a double angle connection to work as long as I strip the flanges on the beam (and use a different design software program). Thank you for all the input.
@KootK I appreciate your input, but I have too many limiting factors for each of these approaches:
- connections on all sides of the column so I would not be able to add anything to the side faces to stiffen them
- 135 kips load was all I could get them to come down from the original 150 kips...
@TehMightyEngineer I have tried looking at a stiffened seated connection, but have ended up with excessive punching shear in the column. I will see if using an angle seat with a stiffener will work for this connection. Thank you.
I am contracted to design a connection for a W14x283 beam to an HSS10x10x3/8 with a reaction of 135 kips factored load (AISC 360-10). There is not enough depth in the W14 to make an adequate connection for this amount of load so I had planned to add on to the bottom of the member with a...
I have been asked to design two different frames and connections for some interior doors. The first design is for hanging toilet partitions where the frames connect to the bottom of an overhead beam and are also attached at the back wall for stability. The second design is for a metal rolling...
