Missile Impact Resistance of a Metal Mesh Roofing System

Abstract

This paper presents the results of impact tests on a roof system constructed with expanded metal mesh welded to a steel frame. The roof system was designed to be installed on a masonry structure that will protect an emergency power generator at a special-needs hurricane shelter during 177 km/h winds. The structure and roof system must meet the windborne debris impact criteria for large missiles from ASTM Standards E1996-09 and E1886-05, which state that the system must resist penetration by a nominal
