Original Abstract

Numerous failures of bridges are recently registered - Troja footbridge in Prague, Czech Republic, 2017, Ponte Morandi motorway bridge collapse in Genoa, Italy, 2018, and many others (https://en.wikipedia.org/wiki/List_of_bridge_failures). Many countries worldwide are currently experiencing a problem of aging and deterioration of reinforced concrete bridges and their remaining reliability for the actual traffic - the question of structural safety is becoming more and more important. Several current standards advocate probabilistic approaches, utilization of mathematical models and design of structures for durability, i.e. time-dependent limit state approach (LS) with service life consideration: ISO 13823 and the fib-Model Code. In such advanced reliability assessment, material nonlinearities, material deterioration, traffic load as well as several types of uncertainties are considered.
