Warping Spring and Warping Restraint

How can I define a warping spring or a warping restraint?


Answer:

After activating Torsional Warping in the Base Data, you can define warping springs and warping restraints. For this, select the Transverse Stiffeners option in the "Edit Member" dialog box; see Image 01.

In the "Transverse Stiffener" tab, you can create several transverse member stiffeners and define the necessary parameters using the "New Transverse Member Stiffener" button. For the "End plate" stiffener type, the resulting warp spring is determined automatically; see Image 02.

In addition to other variants, you can also define a rigid warping restraint or user-defined warping spring stiffness under the "Warping restraint" stiffness type.

As an alternative, you can create member transverse stiffeners using the Data navigator or the menu bar "Insert", "Types for Members", "Member Transverse Stiffeners". In this case, you can use the select function in the "New Member Transverse Stiffness" dialog box to assign them to the corresponding members.
