3.1.10.63. YamamotoBiaxialHDR Element

This command constructs a three-dimensional high damping rubber bearing element with biaxial shear springs distributed in the local y-z plane. Axial and rotational stiffness remain zero. Use with -ndm 3 -ndf 6.

element YamamotoBiaxialHDR $eleTag $iNode $jNode $Tp $DDo $DDi $Hr <-coRS $cr $cs> <-orient <$x1 $x2 $x3> $yp1 $yp2 $yp3> <-mass $m>

Argument	Type	Description
$eleTag	integer	unique element tag
$iNode $jNode	integer	end nodes
$Tp	integer	number of rubber layers
$DDo	float	outer diameter
$DDi	float	inner diameter
$Hr	float	height of rubber layers
$cr $cs	float	coefficients for scragging model (-coRS; optional; default 1.0)
$m	float	element mass (optional; default 0.0)

Note

Valid Element Recorder queries include globalForce, localForce, basicForce, localDisplacement, and basicDeformation.

Example

1. Tcl Code

element YamamotoBiaxialHDR 1 1 2 20 0.6 0.0 0.15

2. Python Code
