Bracing structures

[davidVGKKE]

Hi all, hopefully everybody is great.

I have a frame comprised of I beams as we can see in the Picture below. When I ran the calculation the profiles weren't approved by Robot.

Hence, I created a label named column_test and added some braces in buckling Y and buckling Z.

As we can see in the frame, (in the column 2 for instance),  the only existing brace comes from an adjoining horizontal bar(bar 2), but yet again, as we can see in the buckling Y and Z window others braces were created in other to get the calculation approval of column 2.

My question is, If I decide to build this frame, do I have to provide in my drawing , made for instance in autocad, bars or anything else that brace the column 2 at the points considered in buckling Y and buckling Z the existence of braces ? (Because there is nothing there just fields where filled in the buckling window, furthermore, the real structure have to work as in the model).

If at the design stage you assumed some restrains at these locations (and yo decided to skip them in modelling e.g. they don't influence internal force distribution in the model you created) you should have them in real structure. If they don't exist you shouldn't enter these locations as restrains and design larger sections instead.
