Cracking an Open Safe: More HAZUS Vulnerability Functions in Terms of Structure-Independent Intensity

Abstract

In another work, the “open safe” of the HAZUS-MH methodology was cracked to create seismic vulnerability functions that honor all HAZUS-MH methodologies and data, yet that appear in the form of tables of mean casualty rates (indoor deaths and injuries as four fractions of total occupancy) versus a structure-independent intensity measure, in particular, _Sa (0.3 sec,5%) or _Sa (1.0 sec,5%). In this work, mean repair cost is tabulated against both these intensity measures, for various combinations of model building type, code design level, occupancy class, seismic environment, NEHRP site soil class, magnitude range and distance range.
