Hi !
I've done a push over analysis on a xlam structure formed by 3 floors. I've applied two action groups: one for the modal deformation and the other one proportional to masses. I obtained two push over curves. The first one has low resistance (F max is lower= 382 kN)but it has more ductility (2.40) because I placed connectors of second and third floors so that they plasticizing all together. The second one has more resistance (500 kN) but at the time it has less ductility (1.76). The question is: which action group have I to take into account to calculare structural ductility? The object of my work is to validate the behaviour q. If I choose the first curve I've more ductility and so an higher beahviour factor but If I choose the second one I achieve less ductility.
Thank you so much
