Specifies the cross section twist and torque relationship for beam sections.
Twist component ().
Torque component ().
The behavior of beam elements is governed by the generalized-stress/generalized-strain relationship of the form:
The BSTQ command, one of several nonlinear general beam section commands, specifies the cross section twist and torque relationship 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.
