The provisions of chapter 6 of EN1998-1-1 (EC8) must be included in Robot's calculations which concern Steel buildings for seismic response.
It is a major subject in seismic areas where Robot has only a limited use in Steel structures until now. Robot’s calculations concern only elastic behavior against seismic action and can be used only if we consider a value of seismic behavior factor: q=1.00-1.50. At the moment it is not allowed in Robot to be used q>1.50..
