Originální abstrakt
Nonlinear finite element method and advanced stochastic package were coupled in order to account uncertainties, randomness and spatial variability of material properties in computer simulation of structural behaviour and failure. The nonlinear FE program ATENA contains advanced constitutive models for concrete based on damage mechanics, fracture mechanics and plasticity theories with smeared crack approach. The advanced stochastic simulation software FREET is employed for the stochastic treatment. New and updated (significantly improved) methods were developed and verified in the simulation of uncertainties, e.g. small-sample simulation of Monte carlo type Latin hypercube sampling for both random variables and random fields with focus on correlation control among variables, accurate representation of random fields based on spectral decomposition of covariance matrix and employing very small number of underlying random variables, hierarchical nonlinear material models etc.
