Life-Cycle Performance and Cost Analysis of Steel Bridges

Lead University: Lehigh University
PI: Dan M. Frangopol, Dept. of Civil Engineering
PA Industry: ArcelorMittal Global R&D

The objective of this research is to apply a novel integrated framework using structural health monitoring and reliability methods for improved bridge management under uncertainty. Through the use of new technologies employed for structural health monitoring and reliability approaches, the project is expected to have significant impact on bridge lifetime management practices. This project will apply the developed framework to life-cycle performance and cost analysis of steel bridges.

Outcomes from this project are relevant to the management of the Nation's steel bridge infrastructure, and so should provide significant economic and social benefits to Pennsylvania where the vast population of bridges are made of steel. Pennsylvania companies such as Arcelor Mittal will benefit from this project by using a life-cycle cost model that will clearly indicate the economic advantages of new solutions for steel bridges in terms of material and configuration which provide maintenance-free service during the whole bridge lifetime.
