Realistic properties of wrought iron in New South Wales bridges based on material testing and metallurgical examination

The aim of the paper is to determine appropriate properties of wrought iron (WI) used in the construction of bridges during the period 1865-1905 in New South Wales (NSW), so that these properties can be used to determine a more realistic load capacity of these bridges. The paper also briefly describes the sampling technique carried out to determine the properties of WI, without compromising structural integrity. There are about twenty two wrought iron (WI) bridges built during this period. The design load was significantly lighter than the current general access vehicle loads and restricted access vehicle loads. As at 2006, materials from fourteen WI bridges were sampled and tested. This paper is based on test results available from twelve bridges to determine yield stresses, ultimate strength, ductility and weldability.
