recorder options for base shear and PID
« on: June 09, 2021, 06:40:03 PM »
Hi,

Is there a way to get the total base shear of the frame as one single EDP? I can record individual base shear values separately, but then I don't know if the maximum values happen at the same time. So I can't add them together. That is why I was wondering if there is a recorder command for frame's maximum base shear?

I can see that we can get maximum interstory drift as an EDP as well. But what is the recorder for that. Because whatever is done for PID, I might be able to use that for reactions as well.

Thank you,
Azin

Azin,

you could use the UserDefined EDP with some opensees scripts (the first would create recorder recording reactions at all base nodes or ele forces, the second would be the post processing script, that would open the recorder and sum whatever columns)

ps. thanks for the papers.
