Collapse Recorder

[almouayedbellah-nafeh]

Dear Professor Zhu,

This is not an "issue" but it is more of an inquiry.
I was wondering whether the progressive collapse algorithm, previously developed for OpenSees in Tcl by Mousalam et al. [1-3] and implemented within an infill removal example on OpenSees wiki as a recorder, is implemented in OpenSeesPy?

Thank you very much in advance for your assistance on the matter.

Kindest Regards,

Al Mouayed Bellah Nafeh

I think I can add it. Can you write a document for it?

[almouayedbellah-nafeh]

Thank you for your reply.

Perhaps I can be of help if you can provide me with more information on what sort of document you require.

What would be useful is a description of the recorder and the different options and arguments.

Please find attached the document you have requested.

Unfortunately, I do not have access to the source code of the progressive collapse recorder and therefore my contribution is limited to the information provided on the OpenSees wiki.

I ask of you to keep me updated on the status of implementation and I remain at your disposal for any inquiry or any assistance I can offer.

I added the recorder and will be available next version. But the document is not complete. You can check the recorder document to complete it later
