Problem Description

Incorrect MSRS analysis results when flexible joint or nozzle elements used

Reason

The results for a multiple support response spectrum (MSRS) analysis are incorrect when a flexible joint or nozzle is included in the model.

The following considerations are provided below to assist in your evaluation of the potential impact of this defect on the results.

1. Evaluate whether this defect has affected any existing models by considering the criteria below

a. Is model built in version 9.2 or later?
b. Does the model have a flexible joint or nozzle?
c. Do any of the response spectrum load cases have the MSRS option checked?

A ‘No’ to any of the above criteria means that this defect does not affect the model’s results. No further consideration for this model is necessary.

Solution:

AutoPIPE shall calculate the correct stresses for an MSRS analysis when a flexible joint or nozzle is included in the model.

Additionally, to assist in the screening of the models created in previous program versions for any potential impact by this defect, the program shall automatically examine the model database after opening the model and generate a report (model name + "_8788.TXT") stating whether the model should be re-examined or not.

Avoidance:

None
