The 7 degrees of freedom module provides an additional type for line elements besides the already available rib, truss and 6DOF beam element. The 7DOF element also has the 3 rotational and 3 translational degrees of freedom just like the traditional 6DOF element, but with its 7th degree of freedom, it is able to consider the warping effect, and bimoment as the internal force representation of warping.
Constrained warping can significantly affect the stress distribution in thin-walled beams and columns -typically steel members-, which should be considered in the design.
Warping is also important if the members of the structure are sensitive to lateral-torsional buckling. Stability failure modes, such as torsional, lateral torsional, or interaction modes can only be evaluated using the 7DOF finite element.
