Problem:
If an inclined support had a friction coefficient with Ultimate Force Gap enabled and values; would the analysis consider the Friction coefficient for any pipe movement after the breakaway force value was meet?
Solution:
Yes, the results are exactly the same when Ultimate Force Gap is enabled or disabled during a linear analysis.
See modeling approach and results in image below: Friction and Ultimate Force Gaps was not enabled.
See modeling approach and results in image below: Friction and Ultimate Force Gaps was enabled
Note: The Stiffness K1 = the same as the Spring rate, so both modeling approaches on this page are essentially the same
Conclusion, a Non-Linear analysis considers friction when Ultimate Force Gap setting is enabled / disabled.
