Min moment capacity

I'm having trouble understanding what the "min moment capacity" represents. It's reported for the strength checks in the WSDOT Spec Check Report (and a selectable value in the interactive analysis plots), but a moment demand greater than this "min moment capacity" does not trigger a failing status. My original guess was this represents the minimum moment capacity of the girder over it's life (casting to in service), but that does not seem relevant to report during a strength check at a specific time interval. Also, looking at the min moment capacity over the different time intervals shows no change in the value up until the "install railing system and overlay" interval, and the "min moment capacity" does not match the "moment capacity" at any interval. Any information on how PGSuper calculates this value would be appreciated. Thank you.

It is the moment capacity associated with minimum reinforcement. See LRFD 5.6.3.3

If you are ever unclear about

If you are ever unclear about what the software is doing, look in the Details Report. This report gives a very detailed accounting of the calculations performed by the software, included references to the AASHTO LRFD BDS.
