134 9.1 Summary of Research Program Past terrorist events consisting primarily of explosive attacks, including 60% of those against highway infrastructure between 1920 and 2000 (Jenkins and Gersten, 2001) , highlight the need for blast-resistant structures.

135 Complementing the experimental testing program, analytical research to model the response of blast-loaded bridge columns was carried out at various levels of fidelity throughout the research program. Models included simplified methods for predicting loads, such as design charts and equations, as well as software provided by the U.S.

136 To the extent practical, the cross-sectional shape of a blastloaded column should be selected to minimize the intensity of the blast load. Cross-sectional shape affects how a blast load interacts with a column.

potential solutions to improve concrete confinement and protection against spalling and breach. The research described in this report focused primarily on the response of reinforced concrete bridge columns, but additional research on blast-resistant design is needed for other types of bridge components.
