Slip Connection Required?
Slip Connection Required?
(OP)
Hi All,
I have a condition where a wide-flange beam is resting on 2 perpendicular HSS beams. Is this a condition where one of the connections should be a slip connection to allow for thermal expansion? I feel like an all welded connection for both would constrain the top beam. Or is this a case of overthinking about the problem? If a slip connection is required, what is the best detail in this situation?

re: welding at each end, I wouldn't be worried about thermal expansion in a beam this size - worst case your HSS deflects outward a tiny bit, while remaining braced by the beam.

I can't tell from your sketch what the source of temperature difference would be.
