The eleLoad command is used to construct an ElementalLoad object and add it to the enclosing LoadPattern.

load $eleLoad $arg1 $arg2 $arg3 ....

The element loads are only applied to line elements. Continuum elements do not accept element loads. When NDM=2, the beam column elements all accept eleLoad commands of the following form:

eleLoad -ele $eleTag1 <$eleTag2 ....> -type -beamUniform $Wz <$Wx>


eleLoad -ele $eleTag1 $eleTag2 -type -beamPoint $Pz $xL <$Px>


When NDM=3, the beam column elements all accept eleLoad commands of the following form:

eleLoad -ele $eleTag1 <$eleTag2 ....> -type -beamUniform $Wy $Wz <$Wx>


eleLoad -ele $eleTag1 $eleTag2 -type -beamPoint $Py $Pz $xL <$Px>



$nodeTag tag of node to which load is applied.
$eleTag1 $eleTag2 ... tag of PREVIOUSLY DEFINED element
$Wx mag of uniformily distributed ref load acting in direction along member length
$Wy mag of uniformily distributed ref load acting in local y direction of element
$Wz mag of uniformily distributed ref load acting in local z direction of element
$Py mag of ref point load acting in direction along member length
$Py mag of ref point load acting in local y direction of element
$Pz mag of ref point load acting in local z direction of element
$wX location of point load, prescribed as fraction of element length


NOTES:

  1. The load values are reference loads values, it is the time sereries that provides the load factor. The load factor times the reference

values is the load that is actually applied to the node.
