Simplified conservative procedures for the reliability assessment of existing bridges based on the methods applied for the design of new structures may lead to expensive and time-consuming repairs of bridges. Therefore, the proposed project is focused on the development of advanced methods for the reliability assessment of existing road bridges based on the principles of new European standards EN Eurocodes and international documents ISO. Results of previous research projects supported by the Ministry of Transportation of the Czech Republic (MD CR) and also other available sources will be taken into account. The partial safety factors, given in EN Eurocodes for structural design by conservative values, will be modified for the conditions of existing bridge structures, using probabilistic methods. Advanced procedures for the assessment of characteristic and design values of basic variables on the basis of test results will be proposed.
