Original Abstract
Stochastic simulations in the civil engineering context represent a challenge in terms of computational cost and statistical data acquisition. Ideally such effort should be recompensed by the ability to formulate the probabilistic characteristics of analyzed system in objective and rational way. In order to do so, one must not only control the conciseness of the correlated random input variables but also relate this information to a specific dimension, i.e. characteristic length, otherwise an important feature of the probabilistic considerations would be lost and the output variance would depend on the systems discretization, often treated as a black-box parameter. Persistence of such aspect is demonstrated on selected case study utilizing data from an existing bridge and stochastic nonlinear finite element analysis.
