Parameters of a structure seismic analysis depend on a seismic code used during calculations of a structure influenced by seismic impact. Select Spanish seismic code NCSR-02 in the New Case Definition dialog or click Parameters in the Analysis Type dialog.

To complete the seismic analysis according to the rules given in a code, define the following parameters:
- Seismic base acceleration ab / g
- Coefficient of participation K
- Hazard factor
- Soil factor
- Structure behavior factor C
- Direction.
In the lower part of the dialog, the Direction definition and Filters buttons are located.
The details concerning this structure analysis method can be found in the mentioned code.
