Abstract


In this paper the performance based approach to determine the reliability of curved timber beam during the fire is presented. The reliability is preformed with Monte Carlo simulation method, where, in order to reduce the number of simulations, Latin hypercube sampling is applied. The uncertainties are implemented in the advanced calculation method, as randomly generated parameters for both thermal and mechanical analysis. At the end of the paper, the distribution of the mid-span displacement at 30 min, 45 min and at failure time is presented. In addition, failure time that satisfies safety requirement from the Eurocode (β > 3.8) is determined as well.
