Originální abstrakt

The paper is focused on the assessment of existing prestressed concrete bridge by advanced semi-probabilistic methods. The bridge is represented by a non-linear finite element computational model and thus it is necessary to employ efficient methods for estimation of a coefficient of variation (ECoV). There are two practical cases studied presented in this paper: Semr-probabilistic analysis of single bridge girder and application of ECoV methods to bridge structure. It is shown how to determine design value of ultimate load capacity by semi-probabilistic approach in case of single bridge girder and obtained results are compared. Moreover, ECoV methods are applied in the second case study with a limited stochastic model and three analyzed limit states. Employed ECoV methods are compared to the reference value determined by Latin Hvpercube Sampling technique.
