Classification of Structural Models for Wind Damage Predictions in Florida

摘要

The need to predict hurricane-induced losses for $1.5 trillion worth of existing stru tures exposed to potential hurricane devastation in the state of Florida has prompted the Florida Department of Insurance (FDOI) to charge a group of researchers with the task of developing a public hurricane loss projection model. The development of the model and its ability to predict the consequences of a hurricane on a given area of Florida depends on a reasonable estimate of the different types of structures in the building stock, and on an accurate representation of the main structural types. This paper presents the results of a statistical survey of the building population of 9 Florida counties. Based on the results of the statistical analyses, typical structural models for residential buildings were adopted for 4 Florida regions, and their probability of occurrence evaluated. The paper describes the building models and how they are incorporated into the Florida Public Hurricane Loss Projection Model.
