Pushover unloading

[spratikbuff]

I want to do a pushover analysis till a certain drift and then I want to unload the structure till zero load. I have already done the pushover analysis but I can not figure out how to unload the structure till zero load after the structure is pushed to a certain drift level. Can anyone help me in this? I need this urgently.

Thanks in advance

you could simply get the time and switch to LoadControl, the following would unload in 10 steps.

set lambda [getTime]
integator LoadControl [expr $lambda/10.]
analyze 10
