Module Extension
STEEL Warping Torsion

STEEL Warping Torsion is an extension of the STEEL EC3 and STEEL AISC add-on modules. It performs lateral‑torsional (flexural-torsional) buckling analysis of members according to the second‑order theory (P-Delta) with 7 degrees of freedom and application of imperfections with regard to mode shapes.

AISC 360-16 Steel Member and Warping Torsion Design in RFEM

Lateral-Torsional buckling analyses of members according to second-order theory with 7 degrees of freedom

RF-/STEEL Warping Torsion | Features

Applicable for members defined as sets of members
Separate solver that considers 7 deformation directions (u_x, u_y, u_z, φ_x, φ_y, φ_z, ω) or 8 internal forces (N, V_u, V_v, M_t,pri, M_t,sec, M_u, M_v, M_ω)
Nonlinear design according to second-order analysis
Input of imperfections
Calculation of critical load factors and buckling mode shapes as well as the visualization of them (incl. warping)
Integration into member design in the RF-/STEEL AISC and RF‑/STEEL EC3 add‑on modules
Available for all thin‑walled steel cross‑sections

Activation of RF-/STEEL Warping Torsion Add-on Module in RF-/STEEL EC3

RF-/STEEL Warping Torsion | Input

Since RF-/STEEL Warping Torsion is fully integrated in RF-/STEEL AISC and RF‑/STEEL EC3, the data are entered in the same way as for the usual design in these modules. It is only necessary to select the option "Perform warping analysis" in the Details dialog box, tab Warping Torsion (see the figure on the right). You can also define the maximum number of iterations in this dialog box.

The warping torsion analysis is performed for sets of members in RF-/STEEL AISC and RF‑/STEEL EC3. You can define boundary conditions such as nodal supports or member end releases for them.
It is also possible to specify imperfections for the nonlinear calculation.

RF-/STEEL Warping Torsion | Results

The results of warping torsion analysis are displayed in RF-/STEEL AISC and RF-/STEEL EC3 in the usual way. Among other results, the corresponding result windows include the critical warping and torsional values, internal forces, and design summary.

The graphical display of mode shapes (incl. warping) enables a realistic assessment of buckling behavior.
