Yes, it works fine. Thanks Silvia.

Hello Silvia, I was able to obtain the modes from the recorders in OpenSees. In order to make it work it was necessary to include transient analysis on the file (only one step), otherwise it doesn't save the information. I'm copying part of the file that finally works. Thanks, HB -------------------...

Hello, I hope that somebody can help me to obtain the eigenvectors from OpenSees. First I succesfully obtained the periods of the structure for the first 5 modes. Now I want to get the eigenvectors; then I'm using recorders to obtain files with the modes, but the output files are empty. I'm attachin...

Hi, I would really appreciate if you could help me find the reason why I cant find the periods accurately for a 3-story frame using OpenSees. First, I did the modal analysis using OpenSees. Then I obtained some valued for Periods and modes. After that, I used an alternative procedure for obtaining t...

Hi Silvia,

I appreciate your code and your comments. As you well said, I have to check my models in order to match results.

One last questions, with the recorders I used to obtain the eigenvectors I'm getting some files, but these files are empty. How can I make this work?

Thanks,

Hugo

Hi, I'm new using OpenSees, and I have a question I hope you can help me solve. There is this 3 story steel frame that I've been using to implement MPA procedures. First I did the complete process using SAP, and now I'm using OpenSees. My problem is that I can't obtain the elastic modes from OpenSee...
