Moment Connection
Moment Connection
(OP)
Hello,
I have what is essentially a 7' x 7' "I" shape made up of W-shape beams supported by a single HSS column 23' tall at the centroid of the "I" shape. This structure is subjected to lateral/longitudinal/vertical loads. In order for the "flanges" of the "I" shape to remain stable there needs to be a moment connection to the "web". I have reviewed quite a few beam/column moment connections but I have not seen a beam/beam moment connection (apart from the splice connection). Can I cope the flanges of the "web" beams and weld to the flanges of the "flange beams", along with a shear tab? Thanks in advance....

RE: Moment Connection
What's the structure look like? Single 23' tall column supports a 7'x7' "I" section make up wide flange beams? How does this work?

Thanks for the help - it is a support for rigid bus conductors in an electric substation. the "p"s below are where the insulators mount...not much dead load, just problems with wind/seismic horizontal loads. regards - jm1

RE: Moment Connection
1. Wide flanges might have an unbraced length problem or torsional problem. tubes are much better.
2. assuming this is outside a tube is a better shape for corrosion there is les surface area or horix surface to collect water
