Thx RE: The Ground Motion of Earthquakes - ivanveliki - 11-01-2010 Dear budis, All records contains recorded values for accelerations at equal intervals. You can use any of the files in SAP/Etabs. Examine each file in notepad/wordpad to see how much lines you should skip, what time interval was used and how many points are on one line. |
