This paper is focused on a GIS-based assessment of residential building damage caused by the 1994 Northridge earthquake in which the fractions of existing buildings damaged at various percentages of replacement cost are related to a range of seismic parameters. The assessment uses data from safety inspection reports and tax assessor records, both of which were geocoded and linked to seismic parameters derived from strong motion records at 164 different sites. Analyses of strong motion characteristics and their correlations with building damage were conducted with a very large geographical information system (GIS) database for the 1994 Northridge earthquake that was collected, digitized, and organized by researchers at Cornell. Statistically significant regressions have been developed between damage ratio, DR [% of existing structures with damage equal to or exceeding a particular damage factor, DF (% of building replacement cost)] and the magnitudes of various seismic parameters. Regressions developed between DR and scaled seismic parameters (seismic parameters normalized with respect to DF) resulted in predictive equations having a very high degree of statistical significance.
