== Wittig Sinha Equal Floors ==
This is the only RPS feature that the plugin implements. It belongs to the [[RPS_Feature_Group#Simulation_Method| simulation method group]]. This feature implements the seismic ground motion simulation method according to Aspasia Zerva (1992)

=== Feature Dependency ===
The features required by this feature are summarized in the following table:

* A [[RPS_Feature_Group#Location_Distribution| simulation points feature]]
* A [[RPS_Feature_Group#Frequency_Distribution| frequency discretization feature]]
* A [[RPS_Feature_Group#Randomness| randomness provider feature]]
* A [[RPS_Feature_Group#Modulation_Function| modulation function(time envelop)]]
* A [[SeismicLab_Feature#Spectrum| spectrum feature]]

=== Properties ===

* {{PropertyData|StandardDeviation}}: The standard deviation of the excitation.
* {{PropertyData|DominantFrequency}}: The dominant frequency of the earthquake excitation.
* {{PropertyData|DampingRatio}}: The bandwidth of the earthquake excitation.
* {{PropertyData|EnvelopValueAtNinetyPercentDuration}}: The value of the envelop function at 90 percent of the duration.
* {{PropertyData|NormalizedDurationTimeAtPeak}}: The normalized duration time when ground motion achieves peak.
