For decades, blast-resistant design was applied almost exclusively to
military facilities. Since the 1995 Oklahoma City bombing, however, concern for
blast resistance has spread to other sectors as well. These and recent
experiences such as the September 11 attacks have taught us that explosive
blast, whether accidentally or intentionally caused, is another force that needs
to be taken into account.
This guide, which includes a foreword by Dr. Gene Corley, provides structural engineers with a practical treatment of the design of cast-in-place reinforced concrete structures to resist the effects of blast loads. Readers will be able to understand the principles of blast-resistant design, determine the kind and degree of resistance a structure needs, and specify the materials and details required to provide it. Guidelines are provided for detailing requirements for blast resistance and detailing philosophy and reinforcement splicing are introduced for columns, beams, slabs, walls and joints. It includes a chapter devoted to design methods that can protect structures against progressive collapse.
Two federal agencies, the General Services
Administration and the Department of Defense, have developed design approaches
that reflect lessons learned from studying the performance of Oklahoma City’s
Murrah Federal Building after the 1995 truck bombing. This design guide
describes both the GSA and DoD design approaches and includes a detailed example
of GSA’s alternate path analysis. The guide is a practical manual for the
designers of low-rise concrete structures.
