What is the fastest way to model corrugated sheets by means of surfaces in RFEM?

Answer

Trapezoidal sheeting is already available in the cross-section library of RFEM. These cross-sections are primarily used for stabilization measures in the RF-/STEEL EC3 add-on module and as a template for modeling surfaces. A design as a member is thus not possible.

The easiest way is to first model the trapezoidal sheeting as a member. Subsequently, this member can automatically be converted into surfaces (see Figure 01). Thus, the geometry is obtained as a surface model. Curved trapezoidal sheets are also possible. If a curved member is split into surfaces, it is represented by straight segments. If you still want to use curved lines, you can simply rotate the boundary lines accordingly. The exact procedure shows the video.
