    Original Author: Bentley Technical Support Group

    Sept 2013, AutoPIPE V8i 09.06.00.15

    Problem:

    Why does the Hydrotest case show an Allowable K Factor of 0.9?

    Answer:

    From AutoPIPE online help:

    A non-linear static analysis cannot be performed on the hydrotest load case i.e. friction, support gaps and soil yielding are ignored.rotest Loads" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information. 

    Update: AutoPIPE V8i 09.06.01.10 and higher:

     From AutoPIPE online help:

    Hydrotest Non-linear Method

    To enable hydrotest with gaps and friction, check the 'Non-linear' option for hydrotest load set in analysis sets dialog.
