Wind-missile impact capacity of essential facilities

Abstract

Windborne debris during a hurricane may cause damage to building façades, resulting in significant economic losses and injury or death. Recent building codes have adopted variations of the large-wind-missile impact test in order to certify roof/wall components for hurricane resistance. The purpose of this study was to investigate the performance of commonly used Florida wall and roof assemblies under enhanced large-wind-missile impact testing, beyond the basic test specified in the Florida Building Code. Relevant standards specify similar enhanced standards for essential facilities and shelters. Based on a thorough literature review, a list of wall and roof assemblies that had not been tested before was selected. Wall assemblies included wood and metal framing systems and concrete panels. Roof assemblies included metal framing systems and concrete panels. A comprehensive list of wall and roof assemblies that passed the enhanced test was developed. Assemblies that should be avoided in the construction of essential facilities were also noted.
