Reliability of Concrete Column Exposed to Accidental Action Due to Impact

Popis výsledku v původním jazyce

Reliability analysis of a reinforced concrete bridge column exposed to persistent and accidental design situations is based on the application of probabilistic methods. Principles and rules of the Eurocodes and recommendations given in UIC 777-2 R are taken into account. Accidental design situation due to impact caused by the rail traffic under the bridge is considered. Results of the analysis show, that the reliability of the designed bridge column is sufficient at the persistent design situation (thereliabilility index beta is approximately 4,7 for one year). The probability of the column failure given accidental impact of rail traffic determined using probabilistic methods seems to be relatively high, around 3. The total probability of failure forthe bridge column, taking into account both the persistent and accidental designed situation, may exceed the target value 1,3x1/10(exponent 6)(beta = 4,7)recommended in EN 1990.
