An Energy-dissipating System for Blast Mitigation in Structures

The design of buildings for extreme loads has traditionally been conducted on a life safety basis. As a result, buildings often need to be demolished after an extreme event since the cost of repairing the extensive damage is too great. For many buildings, especially critical infrastructure, continued operation after an explosive attack is essential. The use of energy-dissipating methods in a componentized system will enable the protection of a structure and occupants from a blast and permit the rapid repair and re-occupation of the building after an explosive attack.
This study focuses on the characterization of a componentized system utilizing energy-dissipating component assemblies. From this characterization, a predictive theory, based on a single degree of freedom model, is developed and a general design method proposed. The predictive theory and design method are evaluated in field blast tests.
