Rapid Replacement/Construction of Bridges
Sponsors: National Center for Freight and Infrastructure Research and Education (CFIRE)
Participants: P.S. Sriraj
Status: On-going through December 2010
Objective: To advance technology, knowledge, and expertise in the planning, design, construction, and operation of sustainable freight transportation infrastructure through education, research, outreach, and training. The research will focus on two technical aspects of developing innovative methods for accelerated replacement or construction of highway and railway bridges:
1) a bridge replacement/ construction decision-making framework to determine the required level of rapidity in response, appropriate design/construction alternatives, and cost/benefit characteristics of selected processes; and
2) an innovative system for accelerated bridge design/construction.
Strategy: The proposed research will develop: 1) synthesis of current state-of-practices of accelerated bridge replacement/ construction methods; 2) a bridge replacement/ construction decision-making framework; and 3) an innovative system for accelerated bridge replacement/construction.
Program Plan: This study proposes to develop a bridge replacement/ construction decision-making framework using possible Analytical Hierarchy Process (AHP), and explore innovative methods for accelerated construction of highway and railway bridges that explicitly address materials, design and prefabrication of bridge elements, and construction machinery for assembling the structural components.
Expected Results and Products: The findings will be added to a graduate-level course in transportation asset management at the University of Illinois at Chicago.
