Dynamic Nonlinear time history analysis 1

[orpheas]

Hello everyone,
I would much appreciate some help regarding the nonlinear time history analysis performed by etabs. I tried to find some tutorials about that subject but i couldnt find any. If anyone can help by providing me some step by step instructions or a tutorial that i could download i would be very thankfull.

None?

Define your TH function and define TH case, analysis type "nonlinear" using your function(s) and loads or acceleration.

What in your model is nonlinear? Dampers, gaps? Nonlinear TH can be performed if there are NL boundary conditions such as gaps, dampers, or isolators.

Like anything else new, run a couple of small model examples first.
