Protection against blast loads has become a high priority for many government agencies. Blast retrofitting and structural hardening, much like earthquake retrofits, can prove to be costly. For this reason, it is important to understand that any structural element has an inherent capacity to absorb energy and provide some level of protection. An evaluation of an existing structure may allow a designer to utilize the full absorption capacity of a structural element, precluding the need for a blast-specific retrofit. To illustrate this concept, the blast resistances of non-load bearing precastprestressed or tilt-up concrete sandwich wall panels WP are examined. These components are used extensively in modern construction for cladding of framed building systems and often provide a significant level of protection from blast events.
