Specifies the bending curvature and moment relationship in plane XZ for beam sections.
Curvature component ().
Bending moment component ().
The behavior of beam elements is governed by the generalized-stress/generalized-strain relationship of the form:
The BSM1 command, one of several nonlinear general beam section commands, specifies the bending curvature and moment for plane XZ of a beam section. The section data defined is associated with the section most recently defined (via the SECTYPE command).
Unspecified values default to zero.
