InertiaTruss

This command is used to construct an InertiaTruss element object.

element InertiaTruss $eleTag $iNode $jNode $mr

Argument	Type	Description
$eleTag	integer	unique element object tag
$iNode $jNode	integer	end nodes
$mr	float	the inertance or inertial mass of an Inertia Truss

Note

The valid queries to an InertiaTruss element when creating an ElementRecorder object are 'force' and ‘relAccel’, which output the axial force or relative acceleration between two end-nodes in local coordinates (along the element)

This element has been examined for modal analysis and linear/nonlinear time history analysis

Example

The following example constructs an InertiaTruss element with tag 1 added between nodes 1 and 4 with the inertance of 2000.
