Semi-probabilistic assessment of concrete bridge using polynomial chaos and Gram-Charlier expansions

Novák L., Novák D.
pages 289 - 292, full text

The paper presents an application of novel methodology for design and assessment of structures using semi-probabilistic approach. The significant limitation of existing semi-probabilistic methods is an assumption of Lognormal probability distribution of structural resistance described by the first two central statistical moments. In this study, we investigate the possibility of Gram-Charlier expansion described by the first four central moments, which are efficiently obtained directly from Polynomial Chaos Expansion. The proposed methodology is applied for determination of load-bearing capacity of existing structure – the post-tensioned concrete bridge. The obtained results show the importance of the higher statistical moments and their influence on design value of resistance.
