HAZUS-MH Hurricane Model Methodology. II: Damage and Loss Estimation

Abstract

An overview of the damage and loss models used in the HAZUS-MH Hurricane Model is presented. These models represent the last two of five major component models used in HAZUS for the prediction of damage and loss to buildings subjected to hurricanes. The damage and loss models have been validated using damage data collected during poststorm damage surveys and insurance loss data. The HAZUS Hurricane Model represents an advance in the state of the art over most hurricane loss prediction models, in that it estimates wind induced loads, building response, damage, and then loss, rather than simply using historical loss data to model loss as a function of wind speed. A mitigation example is presented that shows the expected reductions in losses achieved by strengthening the roof of a building and adding window protection.
