Hello,

The HAZUS MH EQ CSM is used for the Capacity Spectrum Method described in HAZUS technical manual. This method is described here.

In contrast to the IM-based method, where the equivalent PGA-based fragilities in HAZUS are used for damage and loss analysis, the CSM uses peak floor acceleration and roof drift ratio-based fragilities for the damage and loss analysis. Because two different fragility function databases are used, the auto_population script (PelicunDefault/Hazus_Earthquake_CSM.py) used for the CSM also differs from the one (PelicunDefault/Hazus_Earthquake_IM.py) used for the IM-based methods.

Hope this answers your question.
