Structural Engineering Help Needed

G3750OGR Forum Member SUPPORTING MEMBER

Hello Structural Engineers!

My question is simple (although the answer may not be):

When 2 "I" beams meet each other at 90 degrees, how are they joined?

They are simply welded together as a "T".
The web? of one is cut and they are welded together as shown below:
Joining plates are riveted to the two mated "I" beams on both sides of the joint.
Some other approach? (If so, please elaborate).

If you have seen this or have experience with this in the real world, please weigh in with your thoughts.

Many thanks,

George

Like #2. It's called coping the beam. You are actually cutting the flanges and leaving the web.

Joe is right. They'd cope the adjoining beam flanges and connect with a plate which is typically bolted/riveted to the web of each member.

Thank you, Joe! Confirms my suspicions.

usually, an angle is attached to the end of the beam on both sides and it's then bolted to the larger beam.

See the source image

or welded, note the coping

The photos provided by AlanRail are correct. My degree is in Mechanical Engineering but early in my career I had to step in for the Civil Engineer on a Processing Plant construction site when he took ill. Alan shared the correct approach.
