Outline of Final Research Achievements	In this research project, a collapse assessment method was verified through analysis of building structures damaged in past earthquakes. The method was developed to calculate probability of collapse using structural damage. Through analysis of real damaged structures, the method was verified in specified ranges of less than 5% of collapse probability.
