STATIC LOAD TESTS ON A HISTORICAL STEEL RAILWAY BRIDGE
A series of diagnostic tests were performed on one short-span, two-lane, historical railway steel-girder bridge, in service from 1918, in the line Conegliano-Casarsa, in Italy.In the first phase, were performed physical and physicochemical tests to characterize the component material. Then strains and stress were calculated via FEM analysis, to preview the ultimate strength behaviour of the bridge: these results were compared with a literatures review done, and with technical Italian normative of the National Railway Society (FS-RFI, partner of the investigation). In the second phase, were done real scale tests on one half part of the bridge, dismantled, and recovered in the University laboratory: static load tests were performed till the ultimate state of the member,subjected to a concentrated load in various position. The results, highline the good condition of the members also after a very long service life period-nearly 100 years.
