I have to do a structural analysis on a TEE according to ASME. I'm quite new to this code.
Here's a pic of it:
I have applied:
- internal pressure
- 3 end cap forces normal to counterbalance pressure (pressure times internal area of the pipe)
- A remote load on the top surface of the TEE (some moments and forces - blue symbol in the picture)
I don't know what restraints I should apply.on the two left and right ends of the pipe.
Some people suggest applying a remote load with zero rotations leaving free displacements on the end faces (left and right) of the pipe.
Some other people suggest restraining only rotation with a restraint respect to the pipe axis.See following pic:
I tried both solutions but they don't work. Due to the nature of the remote load shown on the picture I can't use symmetry either.
I'm attahing the model.
Any suggestions ?
