Abstract

The purpose of this study is to develop mitigation systems suitable for use in preventing casualties and injury due to glass window and glass façade failure in public facilities, such as mass transportation terminals, government, sport arenas or hotel buildings, etc. A series of air-blast tests are conducted to validate the blast resistance of laminated glazing system of new elastomeric urethane interlayers. The tests are conducted in a shock tube capable of achieving reflective impulses up to 250 psi-msec which does not have negative phase contribution to the mitigation system performance. Two aspects of mitigation systems are examined, blast resistant glazing utilizing a new elastomeric urethane interlayer and attachment methods. The attachment systems vary in order to determine the influence of deflection and ductility that yields the best results of reducing the loading to the structural elements.
