Project Details

Project Description: 

This is a cooperative effort between the Federal Highway Administration, the Department of Homeland Security, and the Army Corps of Engineers. The study consists of the physical testing of steel suspension bridge elements—constructed for the test program, or obtained from structures in the field—subjected to several types of simulated attack loadings. Two important element of this program are to: (1) Calibrate the vulnerability of older, partially deteriorated materials compared to modern materials. (2) Determine, in detail, material and design variations that have the greatest effects on countermeasure performance. Both will influence the continuing improvement of mitigation measures in this and in related studies.

Goals 

The key project objectives are:

(1) Calibrate for variations in component materials analytical predictions of bridge component behavior under attack loadings.

(2) Calibrate the predicted performance of currently used mitigation measures under these bridge material variations.

(3) Test and evaluate mitigation materials and retrofit hardware now under development.
