Shear Panel and Rotational Restraint

Tips & Tricks

To stabilize the components bearing stability risks, it is possible to define a shear panel and/or a rotational restraint in RF‑/STEEL EC3. Optionally, trapezoidal sheets, bracings or individual purlins can be taken into account.

For example, to define sandwich panels, you can enter the rotational restraint as well as the shear panel manually as a single value. Also, you can select powder-actuated fasteners according to DIN EN and the consideration of cross‑section deformation. The calculation of the rotational restraint is performed according to EN 1993‑1‑3. The calculated stiffnesses are considered in the eigenvalue solver of RF‑/STEEL EC3 and thus lead to the exact critical load and to the design improvement.
