Dialog elements
 To complete the seismic analysis according to the rules given in this code, define the following parameters: 
- Structure class 
 
- Site 
 
- Zv, Za, v and K 
 
- Direction: Horizontal or Vertical. 
 
  
 The details concerning this structure analysis method can be found in the mentioned code. 
-  Auxiliary case 
 
-  Ignores the selected case during the calculations. 
 
- Base Shear 
 
- Opens the Base Shear dialog which allows you to specify how to take into account base shear. 
 
- Eccentricity definition 
 
- Opens the Definition of mass eccentricities dialog which allows you to consider the mass displacement by an eccentricity in the seismic analysis. 
 
- Direction definition 
 
- Opens the Direction dialog which allows you to define the direction of the spectral/seismic excitation. 
 
-  Filters 
 
-  Opens the Filters dialog which allows you to determine the number of modes considered during the dynamic analysis of the structure.
