Improved load rating assessment of Princes Bridge through load testing

Located on one of Melbourne’s busiest roads there was pressure on Melbourne City Council to assess Princes Bridge for the new higher mass vehicles specified for the Mass Limit Review (MLR). A subsequent desktop analysis suggested the bridge was significantly under strength for the higher loads and extensive strengthening was proposed. Council originally proposed to design, document and tender the strengthening work based on the desktop analysis. With such a complex structure it was apparent there would be benefits in taking the assessment to an increased level of investigation. A successful alternative proposal was put forward which included a diagnostic load test on the bridge. The objective of the performance test was to develop a calibrated structural model of the bridge from which strengthening design could be based. This paper will investigate that test and subsequent findings which resulted in significantly reduced strengthening requirements.
