Dynamic Impact Factors on Existing Long-Span Steel Truss Railroad Bridges

The objective of this project is to develop a novel methodology to determine live/dynamic load impact factors on long-span steel truss railroad bridges caused by modern high-speed trains. The methodology will be based on analytic formulation, finite element modeling, and field testing on a real bridge. The results from the project work should contribute significantly to improving railroad safety and reduce the costs of upgrading existing railroad bridge structures to accommodate high-speed rail service, predict remaining life, improve the rating of such structures, and increase structure safety and reliability. The products of the project should, are expected to be highly relevant to railroads, state departments of transportation, and industries dealing with railroad bridge design, construction, and maintenance.
