Dear All

Is there any extra value adding to Tee's SIF for barred tee?
Please share your experience regarding barred tee SIF.

If you have nozzle loads that rely on the barred tees, you should look at them as though they're rigid.

If you're concerned about the tee itself, the bars' design will have an impact on the SIF and rigidity. However, these will be difficult to quantify. If I were pressed to calculate stress in the tee, I would export loads from CAESAR into an FEA analysis.
