Beam Section Types

A beam element is characterized by its cross section. This cross section is defined by a *BEAM SECTION card. All beam sections which are not rectangular (including square) or elliptical (including circular) are considered as “beam general sections” and are internally expanded into a rectangular cross section (C3D20R-type element) and the actual section of the beam is simulated by an appropriate integration point scheme. A section type is characterized by a finite number of parameters, which must be entered immediately underneath the *BEAM SECTION card. A new section type can be added by changing the following routines:

Right now, the following section types are available:
