Flat bars can be described as "Welded Sections" in the library using the parameters b and d. When entering the parameters, it is important that the width b is defined as larger than the thickness d according to the cross-sectional scheme. Only in this way is it possible to ensure that the element thickness is applied correctly in the equations. The thickness is included with the third power; for example, in the determination of the torsional moment of inertia.
If the strengthening is arranged vertically, as shown in the picture, the flat bar must also be defined by b > d. Before placing the bar, it can be rotated 90° in order to set the correct position.
As an alternative, flat steel can be set as a normal element by means of the start and end nodes.
