*SetBeam() - symmetric circular cross section

Sets the properties of a symmetric beam pair with circular cross section.

Syntax

*SetBeam(beam_name, LEFT|RIGHT, CIRCULAR, 
                              len|AUTO_LENGTH, 
                              E,            G, 
                              OD,           ID,
                              AS,           CRATIO, 
                              ratio)

Arguments

beam_name: The variable name of an existing beam pair.; Data type: varname
LEFT RIGHT: If LEFT is specified, the properties are assigned to the left beam, and the right beam properties are made symmetric to the left beam.; If RIGHT is specified, the properties are assigned to the right beam, and the left beam properties are made symmetric to the right beam.
CIRCULAR: This argument indicates the cross section of the beam is circular.
len: len specifies the undeformed length of the beam.; Data type: real
AUTO_LENGTH: AUTO_LENGTH indicates that the undeformed length of the beam is calculated automatically using the end points of the beam.
E: The Young's modulus of elasticity.; Data type: real
G: The shear modulus of elasticity.; Data type: real
OD: The outer diameter of the beam cross sections.; Data type: real
ID: The inner diameter of the beam cross sections.; Data type: real
AS: Shear area ratio of the beam.; Data type: real
CRATIO: This argument indicates the structural damping matrix is the ratio of the stiffness matrix.
ratio: Ratio for calculating the damping matrix.
