SMART International Symposium for Next Generation Infrastructure: A New Approach to Bridge Infrastructure Management


Published on

A presentation conducted by Ms Maria Rashidi, SMART Infrastructure Facility, University of Wollongong.
Presented on Wednesday the 2nd of October 2013.

The maintenance of bridges as a key element in transportation infrastructure has become a major concern due to increasing traffic volumes, deterioration of existing bridges and well-publicised bridge failures. The main goal of this study is to develop a requirements-driven decision support methodology for remediation of concrete bridges with the aim of maintaining bridge assets within acceptable limits of safety, serviceability and sustainability.The proposed model includes two phases:
Phase one is focused on condition assessment and priority ranking of bridge projects which makes use of an integrated priority index addressing a variety of factors. Phase two includes a multi criteria decision making technique which is able to select the best remediation strategy at both project and network level. The modified Simple Multi Attribute Rating Technique (SMART) is used as a decision analysis tool that employs the eigenvector approach of the Analytical Hierarchy
Process (AHP) for criteria weighting

SMART International Symposium for Next Generation Infrastructure: A New Approach to Bridge Infrastructure Management

  1. 1. ENDORSING PARTNERS A New Approach to Bridge Infrastructure Management The following are confirmed contributors to the business and policy dialogue in Sydney: • Rick Sawers (National Australia Bank) • Nick Greiner (Chairman (Infrastructure NSW) Monday, 30th September 2013: Business & policy Dialogue Tuesday 1 October to Thursday, Dialogue 3rd October: Academic and Policy Presented by: Ms Maria Rashidi, SMART Infrastructure Facility, University of Wollongong
  2. 2. A New Approach to Bridge Infrastructure Management Presented by: Maria Rashidi
  3. 3. Research Significance    There are approximately 2.5 million bridges on the global higher transportation network. 20% deficient Almost 500,000 bridges require remediation and improvement.
  4. 4. Mississippi River bridge collapse    In 1990: A rating of "structurally deficient," citing significant corrosion in its bearings. In 2005: Rated as "structurally deficient" and in possible need of replacement. On August 2, 2007, the Governor stated that the bridge was scheduled to be replaced in 2020.
  5. 5. Entre-os-Rios Bridge Collapse    Collapsed in 2001. The collapse was caused by the failure of a support pillar that came under increased pressure from river water following a period of heavy rain. 70 people were killed.
