I am trying to determine the best way to model a size on size 36" split tee used for a hot tap and bypass.

I notice in "SIFs & Tees" there is a Type 17: Full Encirclement Tee. This allows you to enter a thickness of the split tee under "Pad Thk". However, from what I can tell, it does not include the extra weight of the split tee thickness when I run a restraint summary. My 36" split tee is 2700lbs; so not insignificant by any means.

Is there a better way to incorporate the added thickness, and get the proper weight and SIF?


Thanks!

You could add a downward force at the intersection.

I would avoid changing the thickness and OD as this alters the SIF calculation.

Or you may change the thickness and OD and override the SIF values.

You have two goods suggestions above.

Defining a tee (or SIF) in CAESAR II does not set the element cross section or modify system weight or mechanical strength - it simply determines the SIF (and SSI) to be used in Code stress calculation.
