Frame load high span ratio

[zhangs]

I analyzed the concrete frame supported by the corner brace. When I analyzed the frame with the same height and different span, I found that his displacement load curve was not very different. I felt that it was a matter of self-weight, and I added a certain load but the difference was not obvious

The gravity load is not added to the loadPattern

I reloaded it and there's not much difference

I don't understand what you are trying to compare. Two of them have no braces. They are not the same model.
However, probably changing only the span is not going to influence a lot the shear strength given by the same 2 columns
