The details for the lateral-torsional buckling analysis are defined separately for members and sets of members. The following parameters can be set:
Support Type/Lateral-Torsional Buckling Load
- Available options are Lateral and torsional restraint, Lateral and torsional restraint or Cantilever
- Special supports are possible by specifying the degree of restraint βz and the degree of warping restraint β0. In this section as well, you can consider the elastic warping restraint of an end plate, a channel section, an angle, a column connection, and a beam cantilever by specifying the geometry dimensions.
- As an alternative, it is also possible to enter the lateral-torsional buckling load NKi or the effective length sKi directly
Shear panel
- A shear panel can be defined from a trapezoidal sheeting, bracing, or a combination of these
- Alternatively, you can enter the shear panel stiffness Sprov directly
Rotational restraint
- Choose between continuous and discontinuous rotational restraint
Position of Positive Transverse Load Application
- The z-coordinate of the load application point can be freely selected in a detailed cross-section graphic. (upper chord, lower chord, centroid)
- Alternatively, you can specify the data by selecting them or entering the data manually.
Beam Type
- For standard sections, the rolled beam, welded beam, castellated beam, notched beam, or tapered beam (web or flange welded) options are available
- For special cross-sections, it is possible to directly enter the beam factor n, the reduced beam factor n, or the reduction factor κM
