Beam Type
In FEM mode, only, select the type of beam you want to define on the Beam Definition dialog box. You can define two types of beams:
Beam—A beam has an assigned material, Y direction, beam section(s), beam orientation(s), and beam releases. You can specify different beam section shapes and sizes for the beam ends in FEM mode.
Truss—A truss is a special kind of beam that has properties that define its material and cross-sectional area. You cannot define the orientation or release properties for a truss. A truss has no rotational DOF, and experiences no bending or torsional effects under load. Truss type beams are displayed as circular sections where the areas of the circular sections are calculated by using the parameters of selected sections.
