This command is used to construct a TimeSeries object which, similar to a Path TimeSeries, the load factor obtained is dependent on a series of points obtained from a file. The difference is that the file is obtained from the PeerNGA strong motion database using an internet connection.
| uniaxialMaterial PeerNGA $tag $eqMotion $factor <-dT $dT> <-nPTS $nPts> |
| $tag | unique tag among TimeSeries objects. |
| $eqMotion | the PEER NGA name of the motion (a string containing the earthquake name, station & dirn) |
| $factor | factor to be applied to the data points, if accel record type you want to specify G |
| $nPts | optional, if provided will set the variable nPts equal to number of data points found in record |
| $dT | optional, if provided will set the variable dT equal to time interval between points in the record |
NOTES:
- If the time in the domain does not match a data point in record, linear interpolation is performed between nearest points in record.
- The command can be used with the results obtained from the searchPeerNGA command (hence the craziness of the $eqMotion names).
EXAMPLE
To create 2 time series for two horizontal motions recorded for the Borrego Mtn 1968-04-09 earthquake recorded at the USGS 117 El Centro Array #9 station
timeSeries PeerNGAMotion 1 /BORREGO/A-ELC180 $G -dT dt -NPTS nPts
timeSeries PeerNGAMotion 2 /BORREGO/A-ELC270 $G
