BAR DIAGRAMS ENVELOPE - Bent Moment Values

[Ievgen]

Hello. Please explain me what is the differenece between 2 diagrams of bent moments. Why does it have two lines?

It only has them while load combination is set (USC+ or USC-) not single load, and why does it show 2 support reactions?

[Romanich]

Because ULS+ and ULS- an envelope combinations.

[Ievgen]

and what is the sense? If only it was possible to show values of it, otherwise what does it show? 

[Romanich]

In ULS+ you can see min and max values that was received from automatic combinations ULS for selected component.

[Ievgen]

Yes, I understand that. I was asking about if it was possible to get know what value did it have. Or it just shows that some other combinations have different values?

Robot always displays two 'lines'  (also when they have the same sign) that represent max and min values for selected load cases. In the situation when one of them was drawn 'above' the bar the min. value would be e.g. -100 rather than 0.
