*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.
- 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.
- CIRCULAR
- This argument indicates the cross section of the beam is circular.
- len
- len specifies the undeformed length of the beam.
- 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.
- G
- The shear modulus of elasticity.
- OD
- The outer diameter of the beam cross sections.
- ID
- The inner diameter of the beam cross sections.
- AS
- Shear area ratio of the beam.
- CRATIO
- This argument indicates the structural damping matrix is the ratio of the stiffness matrix.
- ratio
- Ratio for calculating the damping matrix.
