Type S2 Earthquake

Type S2 Earthquake

Type S2 Earthquake

(OP)
Hi all

I am working with an earthquake design and have a question.

I have i response spectrum, so far so good, but would for verification purposes like to run a time-history analysis. My problem is that I don't have the required time-history data.

Does anybody know where I can find time-history data for a S2 Earthquake according to IEC 60980. Any source to download data or buy a book?

Any help is appreciated

Thomas

RE: Type S2 Earthquake

I am unfamiliar with IEC 60980, but I can help you.

Please specify the coordinate points that define the response spectrum and the damping value.  I can then synthesize a time history to satisfy the spectrum.

Hi Tom

Thank you for your reply.

That offer sounds intresting. I looked att your site and noted that you have software that does exactly what I ask for (srs_syn.exe and jsynth.exe). If my assumption is correct then can you let me know, I will simply join and download. It's the first time I encounter the problem but I know it will occur again because this type of project will be arouns for a while.

Regards

Thomas

Thomas,

Yes, please try the jsynth.exe and srs_syn.exe programs.

I can modify them if necessary to meet your specification.

I just wanted to let you know that I downloaded your software and it works just fine. At first it didn't look to good because I thought I would have to manually input all the time-history data into the FEM-software manually but but today it is very simple and nearly automatic.

And your software solved the problem in an elegant manner (at least in my humble opinion).

Thanks

Thomas

RE: Type S2 Earthquake

You can modify  any earthquake records to satisfy the spectrum. to get the earthquake records, you can try to browse PEER database. I suggest you to use common earthquake records like El Centro or Loma Prieta.
