Application of extreme value theory for size effect of concrete structures

conference paper

Czech

Clanek zacina diskusi o nejdulezitejsich rysech teorie statistiky extremnich hodnot a pozdeji toto aplikuje na vliv velikosti betonovych konstrukcÍ.

The paper begins by discussing some fundamental features of the statistics of extremes important for the computational modeling of the statistical size effect, whose asymptotic behavior is not correctly reproduced by the existing stochastic finite element methods. A simple strategy for capturing of statistical size effect using stochastic finite element methods in the sense of extreme value statistics is suggested. Such probabilistic treatment of complex fracture mechanics problems using the combination of feasible type of Monte Carlo simulation and nonlinear fracture mechanics computational modeling are presented using numerical examples of crack initiation problem - size effect due to bending span of four-point bending tests.
