straus 7: modal and non-linear analysis

[Arfy]

Good morning to all, I am doing a job on existing masonry buildings with straus 7.
1) how do I perceive the program that my additional loads must be treated as masses without having to change the density of the material? It seems to me that I have to impose initial conditions within the solver of natural frequency, but I am quite old and I lose blows.
2) how do load increments set in static nonlinear pushover analysis? I press that I have two load houses from static analysis: a first that considers the own weight and a second that considers the carried permanent load. I define a third load case by imposing an accelerated x+ direction but then how to define the load increment table I do not remember.
3) for beam elements how do you define the non-linearity of the material with version 2.2.3? I can not use the mohr coulomb criterion as for plate elements. should I insert the stress deformation curve?
4) always regarding the non-linearity of the material, if I simply define the criterion of breakage to the coulomb mohr as does the program to perceive that such behavior should only apply to compression?
thanks to all

Can no one help me?

Hello, I'm pressing that they're at first with software
1) loads must be inserted as non-structural masses
3) for beam elements non-linearity is defined with a curved moment diagram
I can't help you with other questions.
I hope I've been helpful. Good day

thanks for the suggestions!
