input earthquake acceleration not from PEER database

[Feynman]

Has anyone used earthquake accelerations that were not from the PEER database?

all you nead is a file containing a list of numbers .. the ReadSMDFile proc used in the examples just takes the .at2 files, which contain info in the first few lines about the record and then the record, and creates a new file with just the numbers (i.e. just strips out the header info on the e.q.) .. for example Example3.3.tcl takes ARL360.at2 file and creates
ARL360.g3 file .. it is this file used when constructing the load pattern .. have a look at it
after you run the example .. it just contains the accel numbers.

Thanks but I tried running the example and it said "can't read "dt": no such variable" - how should I fix this?

the ReadSMDFile proc also reads the dt variable that is found with the record .. thi svariable is passed when constructing the uniform motion .. if you just want to use the file of accel records YOU have to supply dt .. so either use set or replace $dt with the actual value.
