Jump to navigation Jump to search

This command is used to construct an interpolated GroundMotion object, where the motion is determined by combining several previously defined ground motions in the load pattern. The command is as follows:


groundMotion $tag Interpolated $gmTag1 $gmTag2 ... -fact $fact1 $fact2 ...

where

$tag unique tag among ground motions in load pattern
$gmTag1 gmTag2 ... the tags of existing ground motions in pattern to be used for interpolation.
$fact1 $fact2... the interpolation factors.
