Over the past twenty years, protection of infrastructure against terrorist attacks has become increasingly important. Anti-Terrorism Planner for Bridges (ATP-Bridge) is a fast-running engineering-level code for predicting damage to bridge components by explosive, thermal, and mechanical threats. ATP-Bridge enables rapid vulnerability assessment for existing bridges and can aid designers to incorporate protective design in new construction. This software is primarily aimed at bridge engineers, but could also help law enforcement or emergency management personnel to assess likely damage to bridge infrastructure from selected human-made intentional or accidental hazards.

Capabilities

  • Damage predictions are made using a combination of empirical models for localized damage and an explicit time-integration finite element code for column structural response.
  • Models in ATP-Bridge leverage over a decade of physical testing and high-fidelity simulation.
  • A straightforward graphical user interface allows the user to create an inventory of components and threats quickly and easily.
  • The component types that can be modeled cover reinforced concrete (R/C) columns with circular or rectangular cross sections, R/C tower panels, steel tower panels, and cables.
