Blast and Impact Loading and Response of Structures
Full Session with Abstracts
It is common in high threat environments to be challenged by providing blast protection to building occupants while the resources, typical construction and labor skills are poor or limited. An important hazard caused by blast loads results from the failure of window glass and are one of the leading causes of injuries during these events.
A mitigation method is to apply anti-shatter film and a catch system consisting of wire rope cables spanning floor-to-ceiling directly behind the windows. This approach allows for a simple implementation with materials generally available in high threat regions with limited installation skills required.
The purpose of this paper is to introduce typical failure mechanisms for this type of hazard mitigation based on experience, recommend design approach and introduce the open air blast testing performed on glass/windows failure backed up with a cable catchment system.
