Reliability of Reinforced Concrete Walls Subjected to Standard Fire Using Advanced and Simplified Methods



The probability of failure of concrete walls subjected to a standard fire on both surfaces is examined. The samples are chosen to match the parameters recommended in the tabulated values of Eurocode 2, which allow a classification of the fire resistance. The probabilities of failure are calculated by means of a Monte Carlo simulation considering the Advanced Calculation Method according to Eurocode 2. To examine the accuracy of a simplified method, the Extended Zone Method is also taken into account. The calculated failure rates of both methods are close to each other, which confirms, that the Extended Zone Method is suitable to determine the reliability of reinforced concrete walls subjected to fire. The calculated probabilities of failure indicate that the tabulated values are mean values with small additional safety elements
