Gh. Chen et Sh. Dai, DETERMINATION OF PARTIAL SAFETY FACTORS OF PARAMETERS FOR INTEGRITY ASSESSMENT OF WELDED STRUCTURES CONTAINING DEFECTS, International journal of pressure vessels and piping, 72(1), 1997, pp. 19-25
Combined with the probabilistic safety assessment method and based on
reliability theory and parameter sensitivity analysis, the margin of r
eliability degree is defined and a method of determining partial safet
y factors is presented. The effect and rationality of the partial safe
ty factors of different methods dealing with the residual stresses are
analyzed in detail. Finally, the method and the results are compared
with those used in PD 6493: 1991. (C) 1997 Elsevier Science Ltd.
