Eurocode requirements on Adriatic arch bridges

There are six major reinforced concrete arch bridges in Croatia located on Adriatic coastline. An important issue in developing maintenance strategy for Adriatic arch Bridges is determining of the structure with respect to increase in loading as well as changes in the requirements of relevant codes and standards over the decades of bridge service. The reliability analysis is necessary to determine the safety margin of existing bridge structures and their capacity to sustain present loads and fulfil all requirements of the new European standards. In this paper some relevant comparisons indicating the influence of Eurocode requirements on Adriatic arch bridges are shown. Additional measurement, inspections and analysis are carried out to prosecute with steps of the reliability analysis procedure.
