Reactions in both direction on simple shear connection
Reactions in both direction on simple shear connection
(OP)
I have a general question I was thinking about today at work. I'm currently designing a framed steel structure to hold a large water tank in South Carolina. The tank structure is part of an industrial structure on the coast. Therefore hurricane loads play a part here. I have intermittent beams orientated so the web is horizontal. This way the major axis of the W Section resists the majority of the loads. I was thinking about the simple shear connection here though. In this case it's probably a good idea to also attache the flanges (vertical) to the supporting member as well. Generally, though how would you handle a horizontal shear connection with reactions in both the horizontal and vertical directions? Would you just check the angle for combined loads and assume minimal prying action in the bolts?

This complicates the connection. As DaveAtkins implies, it would be nice to simplify the connection starting with the way you model the structure.
Assuming you have no other choice but to fix the ends both ways, then here some options
i- Double angle in the web and site welds in the flange
ii- End plate bolted connection
3-Both flange and web site welded
All these are however complicated details and will introduce complicated stresses in the member you attach your beam to. And in your hurricane areas(or seismic areas) things are better when simple(simple stress paths)
If possible, follow DaveAtkins advice, simplify your analysis and make do with double angles or shear tabs.
