The Load> Static Analysis Sets command allows the user to define multiple static analyses (analysis sets) and provide references to these results from separate analyses during post-processing. Analyze > Static or  will analyze all selected static analysis sets.

The Static  option in the Analyze menu enables the user to perform all the selected static analysis sets considering any scenarios of gravity and thermal expansion loads, plus wind loads and/or static earthquake loads if they have been defined.

From inside AutoPIPE with a model opened, select Load> Static Analysis sets... after the screen appears press the "HELP" button for details on all the key features available on the dialog.

To define loadcases to be added to a specific analysis set, highlight a row by left clicking the mouse on the first square in the row, the row should be highlighted black with white lettering, now left click the "Modify" button. In a moment the"Static Analysis Load Cases" dialog should appear. AutoPIPE only activates load case input fields for currently defined load cases. Again press the "HELP" button for details of features available on this dialog screen.

Questions and Answers  

Item #1, Question:

My results does not appear to be considering weight of conents in piping for the analysis?

Answer:
On the "Static Analysis Load Cases" dialog screen is a check box for "Contents", confirm this box is enabled (checked ON) for all analysis sets as desired. Enable this option to include the weight of the pipe contents in the analysis of the gravity (GR) load case. This will cause the program to consider the respective pipe properties settings for all the piping in the model. The calculation for weight of pipe contents is based on the individual pipe ID's:

      A.  Inside diameter of a pipe
      B.  Specific Gravity of Contents (based on water).
      C.  Linear center line distance of a piping for a Pipe ID

Each one of the 4 settings must be configured to correctly consider weight of contents in a piping systems for each Pipe ID and Analysis Set.

Additional information is available to be reviewed in the Tools> Model Listing > Center of Gravity sub report. This option generates a section that reports weight and center of gravity coordinates for all the components in the model. The components are categorized as Valves, Flanges, Flexible Joints, Additional Weights, Pipes (includes straight runs, bends, tees and reducers), and Beams. Weight and center of gravity coordinates for Insulation, Insulation Cladding, Lining, and Contents are also reported as separate categories. Weight and center of gravity coordinates of different combinations of the categories are also reported (see online help for details on this report).
