The article refers to the application of the probabilistic method SBRA (Simulation Based Reliability Assessment) in reliability assessment of a composite steel concrete cross section of roadway bridges. Method SBRA allows to reflect wide spectrum of input random variables, time dependent effects of creep, shrinkage and corrosion of steel section as well as importance of inspection periods in connection with lifetime prediction of structure. The analysis based on fully probabilistic concept is performed using computer program Anthill™ and realized for both elastic and plastic theory of behaviour. Output of this program is the probability of failure Pf, safety function is expressed by histogram. Obtained probabilities of failure Pf are compared with target probability of failure Pd and conventional design method.

Referát je zaměřen na pravděpodobnostní posudek spolehlivosti spřažených ocelobetonových dálničních mostů metodou SBFRA. Metoda SBRA dovoluje respektovat široké spektrum nahodile proměnných veličin ovlivňujících celkovou spolehlivost.Rozbor založený na plně pravděpodobnostním pojetí dovoluje posudek spolehlivosti při uvažování pružné i pružně plastické oblasti působení.
