“…Given that fatigue damage accumulation in decks and main superstructure elements is a common concern to bridge owners and management agencies, there is a high demand for effective fatigue life prediction of fatigue-prone elements of orthotropic steel bridges to ensure bridge health and timely decision making for maintenance and rehabilitation planning. In recent decades, design specifications (AASHTO 2010, Eurocode 3 2005, Canadian code (Canadian Institute of Steel Construction 2007) and approaches to the prediction of remaining fatigue life of OSD bridges have been developed and applied actively in the context of reliable SHM systems (Battista et al 2008;Guo & Chen 2011;Guo & Chen 2013;Guo et al 2012;Guo et al 2015;Kim et al 2001; Anon n.d.; Liu et al 2010;Ni et al 2010;Okasha et al 2012;Saberi et al 2016;Orcesi & Frangopol 2013;Lu et al 2016;Cross et al 2013). Kolstein et al (2007), in particular, present a review of typical fatigue details in orthotropic steel bridge decks and their corresponding testing programmes in European and Asian countries.…”

In this study a Structural Health Monitoring (SHM) system is combined with Bridge Weigh-inMotion (B-WIM) measurements of the actual traffic loading on a bridge to carry out a fatigue damage calculation. The SHM system uses the 'Virtual Monitoring' concept, where all parts of the bridge that are not monitored directly using sensors, are 'virtually' monitored using the load information and a calibrated Finite Element (FE) model of the bridge. Besides providing the actual traffic loading on the bridge, the measurements are used to calibrate the SHM system and to update the FE model of the bridge. The newly developed Virtual Monitoring concept then uses the calibrated FE model of the bridge to calculate stress ranges and hence to monitor fatigue at locations on the bridge not directly monitored. The combination of a validated numerical model of the bridge with the actual site-specific traffic loading allows a more accurate prediction of the cumulative fatigue damage at the time of measurement and facilitates studies on the implications of traffic growth. In order to test the accuracy of the Virtual Monitoring system, a steel bridge with a cable-stayed span in the Netherlands was used for testing.

“…In the study conducted by Battista et al (2008), the volume of traffic was considered according to collected toll data and taken as constant for 2002 and forward from then. Average weights were assumed for all vehicles within each category and the load distributions between front and rear axles obtained from vehicle weighing data.…”

“…Several studies using experiments [2][3][4][5] and analysis [6][7][8][9][10] were carried out to investigate the fatigue of orthotropic steel decks subjected to heavy vehicle loads, while a limited number of studies [11,12] for light-weight vehicle loads were performed. The fatigue of orthotropic steel decks carrying only light-weight vehicles has not been studied.…”

“…[1] One of the probable damages which bridges may experience, due to increasing traffic volume as well as environmental degradations such as corrosion, is fatigue phenomenon. Specifically fatigue cracks have been reported in several types of welded joints of orthotropic deck steel bridges [2]. However, orthotropic decks are widely used in construction of bridges.…”

The maintenance cost of old bridges is rapidly increasing, since many of them are reaching their design life. Hence requirements for remaining life evaluation of existing bridges are overwhelmingly increasing for bridge authorities all over the world. Fatigue phenomenon seems to be a great concern in this regard whereas no theoretical methods can evaluate the remaining life of existing bridges accurately. This paper presents the procedures used for assessment of remaining fatigue life of an aging orthotropic steel deck bridge in Tehran including strain field measurements carried out on critical fatigue details as well as laboratory tests on limited samples, taken from similar details of an identical disassembled bridge. Field measurements have been carried out under normal traffic loading during an 8-day period of time. Laboratory tests are made on samples taken from the most critical fatigue details on a region of high stress fluctuation (mid span) and the same details at a stagnant region (supports location) and compared. Similar results were obtained from both approaches showing the investigated bridges will not experience fatigue failure under the current traffic regime.
