Apply NTH in Two Perpendicular Direction at The Same Time

[Hwoarang]

Hello Everyone

I want to accomplish NTH (nonlinear time history) analysis in two perpendicular directions at the same time (i.e. x and y directions). But I don't know how to do this. I would be appreciated if anybody helps me in this field.

You need to define two acceleration time series and apply them in two orthogonal directions, below is an example

set comp1 "Series -dt $dt -filePath $xFile -factor $GMfatt"
set comp2 "Series -dt $dt -filePath $yFile -factor $GMfatt"

pattern UniformExcitation 2 1 -accel $comp1
pattern UniformExcitation 3 2 -accel $comp2

Thank you so much Dear selimgunay
