Member Hinges

The dialog box for the member end hinges also corresponds to the dialog box for the calculation with 6 degrees of freedom when using the Warping Torsion add-on (7 degrees of freedom). The function of the member end hinges is described in the chapter member end hinges of the RFEM manual. It is not possible to define a hinge of the warping.

Transitional conditions for the 6 degrees of freedom

As with the calculation with 6 degrees of freedom, the connection of members in a common node is assumed to be rigid. The global deformations and rotations are therefore the same at all member ends that meet in the node. Define member end hinges to define the transition conditions of the 6 degrees of freedom u_x, u_y, u_z, φ_x, φ_y and φ_z and to deviate from the rigid connection. In addition to the definition of spring values, non-linearities are also possible.

Transitional conditions for warping

The warping at the member ends is assumed to be unobstructed by default. The bimoment and warping are therefore not transferred to adjacent members. A continuity of warping and bimoment can be achieved by modeling undivided members or by defining sets of members. More information can be found in chapter Sets of Members .

The entry of warp springs in members is possible via the definition of member transverse stiffeners and is explained in the corresponding chapter of this manual.
