“…The role of partial safety factors is to ensure the required level of structural reliability. Probabilistic approximation (FORM [ 2 , 3 , 4 , 5 , 6 ], SORM [ 7 , 8 , 9 ]) or simulation (Monte Carlo, Importance Sampling [ 10 , 11 , 12 , 13 , 14 ]) are an extension of the semi-probabilistic limit state method. The probabilistic approach allows a more accurate and more realistic description of materials, geometric parameters and loads, acting on structures by specifying the type of probability distribution and its parameters.…”
