Blast-Resistant Highway Bridges: Design and Detailing Guidelines

There is a need to protect the nation's bridges from intentional or accidental explosions. The impacts of these loads on buildings and military structures have been studied for many years, but design for resistance to explosive effects is a new area for bridge engineers. Much research and development has been done on the effectiveness of seismic strengthening details for buildings and bridges. It has been suggested that bridge details, used in construction or as a retrofit to resist seismic and other extreme event loads, may serve also to resist explosions and provide a predictable level of protection for such structures. The investigation of these known details for this new area of bridge loading could result in efficient design recommendations, delivered in a relatively short timeframe. Research is needed that will meld knowledge of seismic and extreme event design for new and existing structures, the equally well-known field of blast-resistant design, and the relatively new field of highway bridge blast-resistant design. The research approach will draw on shared knowledge across these fields with initial emphasis on the investigation of seismic design principles and their application to explosion resistance. The objective of this project is to develop design guidance for improving the structural performance and resistance to explosive effects of new and existing bridges.
