Truss Element

This command is used to construct a truss element object. There are two ways to construct a truss element object:

One way is to specify an area and a UniaxialMaterial identifier:

element truss $eleTag $iNode $jNode $A $matTag

the other is to specify a Section identifier:

element truss $eleTag $iNode $jNode $secTag

---

$eleTag	unique element object tag
$iNode $jNode	end nodes
$A	cross-sectional area of element
$matTag	tag associated with previously-defined UniaxialMaterial
$secTag	tag associated with previously-defined Section

NOTE:

• When constructed with a UniaxialMaterial object, the truss element considers strain-rate effects, and is thus suitable for use as a damping element.

• The valid queries to a truss element when creating an ElementRecorder object are 'axialForce,' 'stiff,' deformations,' 'material matArg1 matArg2...,' 'section sectArg1 sectArg2...' There will be more queries after the interface for the methods involved have been developed further.

EXAMPLE:

element truss 1 2 4 5.5 9; # truss element with tag 1 added between nodes 2 and 4 with area 5.5 that uses material 9
