Independence of FEM mesh (localization limiter) (Bažant and Oh, 1983).
Statistical simulation - random input parameters are generated according to their PDF using LHS.
Generated realizations of random parameters are then used as inputs for ATENA computational model. The complex nonlinear solution is performed and results (response) are saved.
Previous two steps are repeated N-times (N is the number of simulations used).
Statistical assessment - the resulting set of structural responses is statistically evaluated: Mean value, variance, coefficient of skewness, histogram, empirical cumulative probability density function of structural response, etc.Probabilistic module - FREET implementation into ATENA
Practical example - PORR bridge in Vienna
upper triangle - presribed correlation matrix
lower triangle - generated correlation matrix
