- Abstract
- The Blast Standards Verification Program Program (BSVP) was sponsored by the U.S. Department of State in support of the Design of Structures to Resist Terrorist Attack Program. The BSV Program was conducted with tow objectives. The first objectives to determine the static resistance and the dynamic response of current embassy (FE/HPE) windows and doors. The purpose of this objective was to identify the level of protection currently provided U.S. embassies. The second objective was to develop a methodology of testing and analysis that would preclude conducting dynamic tests, yet would provide a reliable means of assessing the blast capacity of future window and door designs. A total of ten static and three dynamic tests were conducted during the program. The specimens tested were a window and door obtained from the Norshield Company, a window obtained from Chicago Bullet Proof, two windows and a door from Insulgard, along with a blast resistant window designed by the Waterways Experiment Station. Each of these specimens were static tested to failure. Resulting failures occurred as a loss of bite on the glazing or shearing of anchorage support. From the tests a resistance function was developed for use in a single-degree-of-freedom analysis. A preliminary analysis of the windows and doors was conducted to determine the high-expolsove charge weights required to produce the desired dynamic response. To verify the analysis, full-scale testing was conducted. The results of the tests verified the analytical procedures. It was concluded from the tests that the windows and doors demonstrated an inherent blast resistance. These windows and doors were recommended as blast resistance to the levels indicated. It was concluded that the static tests, coupled with use of the single-degree-of-freedom analysis, predicted the level of blast protection with sufficient accuracy. A proposed method of blast certification of windows and doors was recommended.
