Overall Summary-Controlling Failure Mode, Negative Margin Structure(kg)

[cmcho]

In "Overall Summary" of stress reports, what do you mean by "Controlling Failure Mode, Negative Margin Structure(kg)?
I have some value in this weight description in stress reports, although there was no negative margin component after detail sizing. What I can not understand is every component would be sized by satisfying one of failure modes at minimum margin of safety. Could you explain what it is and when this can happen?

Thanks.

This report field should be the cumulative panel/beam weight for all components where the minimum margin of safety (MS) is negative. I ran a couple test and it appears to be working this way.
 
I am unable to repeat your issue where all of your components show positive MS, yet you have weight reported to this field. Can you provide the XLS report?
