This work presents an analytical methodology to quantify the effect of a readily observable building feature on the seismic performance of a building class using 2nd-generation performance-based earthquake engineering (PBEE-2). Index buildings are designed to span the observed range of values of the important features, to reflect variability within the building class. One set is designed with the feature of interest and another without. Each building is analyzed for collapse probability using PBEE-2 procedures. The effect of the feature is estimated as the ratio of the weighted-average vulnerability of the set with the feature to the weighted-average vulnerability of the set without the feature. I will call this ratio a seismic performance modification factor (SPM). Relating results of an illustration to FEMA 154 (ATC 2002a) validates the methodology.
