Modal with automatic definition of seismic case

  I would like from someone that has used the definition of the load case “Modal with automatic definition of seismic case“ to illustrate the options of this method.

 

  In the “Definition of seismic case group for the direction”, if for instance someone chooses the option X-Y-, does it mean that a simultaneous excitation is taking place in both directions of -X and -Y? And so, what does the title of the automatically generated load case: “Seismic EC8 Exc X-Y-Direction X” (and also “Seismic EC8 Exc X-Y-Direction Y”) means?

  Is the definition of eccentricities getting involved in this title?

 

  Thank you.

This part of this window corresponds to eccentricities, not excitations.

THis X-Y- means both eccentritcities in negative X Y direction considered

 

Excitations here:

  Thank you,

  You confirmed what i was already thinking about that.

  So, the title: "“Seismic EC8 Exc X-Y-Direction X” isn't correct. It should be: "“Seismic EC8 Ecc X-Y-Direction X”. The Exc must be replaced by Ecc.
