3.1.10.12. 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 |
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.
Tcl Code
