Hi there,
I'd like to simulate the hysteretic behaviour of a wall and currently what I'm doing is to define load cases for each direction and displacement and combine the pushover curves in the end. I use the displacement control and define displacements the first few points of the courve from an experimental analysis. There are several problems, for example if I apply a negative load, it is still displayed as a positive load in the pushover curve. I also tried using different initial conditions and continue from the state at the end of another nonlinear case, but this also does not work, especially noch with the wrong definition of the force. Does anyone know a better way to do this? I'd also really like to have one diagram in the end with all the displacements and not having to combine all of them by hand.
Thanks in advance!
