RF-/FE-LTB calculates the individual spring constants automatically.Alternatively, you can use the various options to define the rotational and translational springs from a shear panel.In the case of elastic member foundations, you can manually enter spring constants.The resulting warp spring is determined automatically using the input parameters. It is possible to define a warp stiffening on each node.The support type of each node is editable.Special warping releases applicable for definition of warping conditions on transitionsĬomprehensive and easy options in the individual input windows facilitate the representation of the structural system: Nodal Supports.Determination of value for inclination or precamber by means of eigenvalue analysis.Free arrangement of eccentric nodal and line supports on a cross-section.Graphical selection of load application points on a cross-section (upper chord, centroid, lower chord, or any other point).Easy determination of discrete springs such as warp springs from end plates or rotational springs from columns.Wide range of tools for determining shear panels and rotational restraints (such as corrugated sheets, purlins, bracings).Display of eigenmodes and torsional modes on the rendered cross-section.Optional determination of the limit load factor (critical load factor).Design of members and sets of members with applied torsion (for example, crane girder).Lateral-torsional buckling analysis of any cross-section (also the SHAPE-THIN cross-sections).Determination of critical load factor and thus of M cr or N cr (the factor can be used in RF-/LTB for the el/pl design).Stability analysis of planar continuous members for buckling and lateral-torsional buckling.General stress analysis with warping torsion according to elastic-elastic method.
