Window Blast Design – Hazard Mitigation Engineer

Window Blast Design – Hazard Mitigation Engineer

Explosive blasts create additional overpressure loadings. That are typically not accounted for. In conventionally designed buildings. The performance of building envelopes and cladding components.

So the purpose of blast resistant design is to minimize the hazards caused by a blast as opposed to preventing damages

Performance conditions established by. GSA are categorized by breakage characteristics ranging from 1. Which allows no breakage, to 5, so where breakage debris travels 10-ft or farther from the window.

Mitigation Technoloties

Various approaches may be used when designing fenestrations for blast-resistance. These include particular design of the glass or window frame components; increased anchorage of the window assembly itself; structural augmentation of the surrounding wall structure; or separate shielding systems and mechanisms designed to catch the debris and also use of laminated glass.

Unified Facilities Criteria

The Unified Facilities Criteria (UFC) system provides “planning, design, construction, sustainment, restoration, and also modernization criteria” for all Department of Defense projects. It is accessible through the Whole Building Design Guide electronic media source. A program of the National Institute of Building Sciences.

UFC 4-010-01 DoD Minimum Antiterrorism Standards for

Buildings document was most recently updated in February 2012.

And includes blast resistance criteria for windows in both new and existing facilities. This criteria applies provisions for glazing, framing, connections and supporting structural elements. It includes standards for dynamic analysis, testing and explosive weights associated with respective standoff distances.

In addition to specific requirements for glass size. Lamination, deflection limitation, and testing.  UFC design criteria is generally based on. ASTM F 2248. Given project-specific standoff distance and. TNT-equivalent size.

This load is then used for design of the assembly frame. Glazing frame bite, connections, and supporting structural elements.
