Specifies the axial strain and axial force relationship for beam sections.
Axial strain component ().
Axial force component ().
The behavior of beam elements is governed by the generalized-stress/generalized-strain relationship of the form:
The BSAX command, one of several nonlinear general beam section commands, specifies the relationship of axial strain and axial force for a beam section. The section data defined is associated with the section most recently defined (via the SECTYPE command).
Unspecified values default to zero.
