Considerations for Blast-Resistant Glazing Design

Abstract

When an explosive threat exists building owners should strongly consider using blast-resistant glazing in windows and curtain walls. Architects and engineers have no publicly available tools, procedures, or formal guidelines to aid in the design of blast-resistant glazing. This paper discusses factors pertinent to the design of blast-resistant glazing. It makes specific recommendations concerning window glass types and constructions suitable for use in blast-resistant glazing constructions. It addresses considerations in framing and attachment of blast-resistant glazing to its framing. Most significantly, the authors offer a relatively simple approach to facilitate blast-resistant glazing design in terms of traditional window glass design methodologies for laminated glass and insulating glass fabricated with laminated glass. Use of the blast-resistant glazing design procedure described herein eliminates the need for very expensive blast testing.
