"The Bridge Security Design Manual provides information for structural engineers, planners, owners and others to incorporate effective strategies in bridge projects and make highway systems resilient against terrorist threats. These threats have been a growing concern in the U.S. since the 9/11 attacks. While previous infrastructure security research and practice have focused primarily on buildings, the limited bridge-specific design guidance suggests that bridges protected against common loadings these terrorist threats can impart to bridge components. 'The primary objective of this bridge security design manual is to present state-of-the-art guidance on bridge-specific security planning, extreme loading phenomenology and characterization, and protective design strategies to be used by the highway bridge community in terrorist threat vulnerability assessments of existing bridges, resilient design of new bridge construction, and emergency planning efforts.' The manual covers a broad range of topics, including security planning, material performance, blast phenomenology, mechanics of structural elements, dynamic response of structures, protective design guidance and example designs for several component types (such as concrete towers), and the use of the software tool, Anti-terrorism Planner for Bridges (ATP-Bridge). It is intended to be a resource for broad audiences to better understand bridge security and a reference tool for designers to build protection into bridges and enable the highway systems they connect to function at a high level under a variety of threats. It makes use of the latest technology and research, including the ATP-Bridge tool."
