BSAX
BSAX, VAL1, VAL2, T
Specifies the axial strain and axial force relationship for beam
sections.
-
VAL1 Axial strain component (
).-
VAL2 Axial force component (
).-
T Temperature.
Notes
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, with the exception of temperature. If the temperature is unspecified, the values become temperature-independent.
Related commands are BSM1, BSM2, BSTQ, BSS1, BSS2, BSMD, and BSTE.
