Abstract:

The structure of an existing bridge cannot be assessed using the same nominal parameters and safety factors calibrated for the design of new bridges. The direct use of probabilistic methods allows a determination of the safety and serviceability of an existing structure. The uncertainties involved with load and resistance values in the assessment of concrete bridges are usually lower than in the design stage because the strength and load effects can be estimated accurately by using information from inspections, experimental tests, traffic measurements and other supplementary data. After that, a full probabilistic analysis is performed, as with design code calibration, but for each particular case of study. A practical example is presented, including the assessment of a prestressed concrete bridge, to illustrate the abilities of probabilistic methods to assess existing structures.
