Blast Capacity Evaluation of Glass Windows and Aluminum Window Frames
Abstract
A series of static and dynamic tests were performed to evaluate the blast-resistant capacity of tempered and regular glass windows and aluminum window frames used in buildings at Army ammunition Plants. The test results indicate a maximum blast capacity of 30.3 kPa (4.4 psi) incident over-pressure from 900 kg (2,000 lb) of explosives for 6.35-mm (1/4-in) thick tempered glass panes mounted in rigid frames with a glass area of 1.86 sq m (20 sq ft) or less. For tempered glass mounted in aluminum window frames, the blast capacity was reduced due to frame distortions to 8.27 kPa (1.2 psi) for standard frames, and 17.9 kPa (2.6 psi) for strengthened frames. Design criteria developed based on the test resutls are presented and recommendations are made for testing of thinner glass windows. (Author)
