Dear Experts,

Our client has special requirement to use structural members (H beam, Channel, Angle) as dummy supports, not Pipe to Pipe connections like normal projects. Also, Pad at elbow.

we had calculated equivalent pipe size to modal in CAESAR based on structural member's moment of inertia and allowable loads.

But while analyzing local stress junction i,e Elbow & trunion(H-beam), how to calculate SIF?

ASME B 31.3 Appendix D is for Pipe to Pipe connections, hence cant directly use that calculations into CAESAR, we need to put manually in CAESAR SIF values.

So, we need SIF value.

Please guide us to calculate SIF of structural members welded with PIPE.

Snehal Dave
