He also summarized NRC publications in the area of protective design approaches, objectives of blast effects research, and a strategy for technology transfer.

Barbera, George Washington University Joseph Barbera presented an overview of the human impact of large explosions, the need for understanding the factors important to minimizing injuries and death as a primary action, maximizing rescuer safety as a secondary action, and maximizing response effectiveness. He noted that the hazards are many and complex for example, blast effects, shrapnel and falling or flying objects, structural collapse, smoke, fire, toxic gases, and hazardous materials and dust.

Of great technical interest were cost comparisons for standoff distance and relative hardening in the most general sense, followed by breakdowns of the costs for roofs, walls, and security items. He indicated an immediate need for new bollard design tools, refined standoff design concepts, existing building renovation solutions, better window glazing products, forced entry improvements, and new materials research and implementation.

Government Christopher Veale discussed the incorporation of protective design features into standard measures (those applied to all government buildings) and enhanced measures (those applied in specific cases)

Chapman, Kern Charuhas Chapman & Twohey John Chapman described the blast protection parameters typically applied to buildings designed by his firm; 30 psi to 140 psi blast pressure for new buildings and 3 psi to 15 psi blast pressure for building retrofits. His presentation focused on the blast protection problems confronting architects and the need for a range of possible solutions.

The data surveyed included hospital medical records, physicians' records, building occupant records, newspaper records, governor's records, and survivor memories and records. Their presentation demonstrated that thorough epidemiological analysis can improve the physical design of facilities subject to terrorist bombings.

Tedesco, University of Florida Joseph Tedesco reviewed recent and upcoming conference activities, committee reports, and technology-transfer initiatives of the Shock and Vibratory Effects Committee of the American Society of Civil Engineers' Structural Engineering Institute to address blast effects on structures. That committee is also considering the possibility of preparing independent codes, standards, or design manuals and incorporating some of this type of material into ASCE 7-98, Minimum Design Loads for Buildings and Other Structures.

There is also an interest in obtaining simplified design guidance for cost-effective approaches to providing lesser to moderate levels of blast protection. This includes specific guidance on approaches to and criteria for providing reasonable protection against progressive collapse from moderate-size events and costeffective glazing of window glass, methods for attaching glass to the frame, and techniques for attaching the frame to the wall.

data collection team (analogous to the National Transportation Safety Board's postcrash investigation team) and defining standardized data collection methods and data elements for these teams to use; establishing a national or international clearinghouse for past and future data on bomb blast incidents; and establishing a process for developing and disseminating best practices in building design with input from the public safety community.

Examples might include siting, land, and facility features; safe haven aspects of building design; security issues, including access; other design concerns such as ingress/ egress, blast doors, air supply and protective blast vents, floor, roof, walls and frames (if applicable) ; and glazing and supporting frames.
