*SetBeam() - arbitrary cross section

Sets the properties of a beam arbitrary cross section.

Syntax

*SetBeam(beam_name,ARBITRARY, len|AUTO_LENGTH, E,G,area, ixx,iyy,izz, asy,asz, CRATIO,ratio)

beam_name: The variable name of an existing beam.; Data type: varname
ARBITRARY: This argument indicates the cross section of the beam is arbitrary.
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
area: Area of cross section of the beam.; Data type: real
ixx: Polar moment of inertia of the beam cross section.; Data type: real
iyy: Second moment of inertia of the beam cross section bout the Y axis.; Data type: real
izz: Second moment of inertia of the beam cross section about the Z axis.; Data type: real
asy: The correction factor for the shear deflection along the Y axis.; Data type: real
asz: The correction factor for the shear deflection along the Z axis.; Data type: real
CRATIO: This argument indicates the structural damping matrix is a ratio of the stiffness matrix.
ratio: Ratio for calculating the damping matrix.; Data type: real
