The invention discloses a determining method for the standard values of the stable ultimately bearing capabilities of latticed shell structures. The determining method comprises the following steps: determining a calculation sample size n; calculating the stable ultimately bearing capabilities of n latticed shell structures with initial geometric imperfection; drawing a statistical histogram of stable ultimately bearing capabilities with a certain step size, and assuming that the data are subjected to a normal distribution; carrying out a Kolmogorov-Smirnov test, and determining the correctness of the assumption that the stable ultimately bearing capabilities of the latticed shell structures are subjected to the normal distribution; and calculating estimates of the mean and the variance of the population of stable ultimately bearing capabilities of the structures with the maximum likelihood method, and calculating the standard values of the stable ultimately bearing capabilities of the structures with the probability level 0.977. The relative errors of the standard values of the stable ultimately bearing capabilities of the latticed shell structures are determined as follows: the relative errors of the stable ultimately bearing capabilities of the latticed shell structures is in direct proportion to the reciprocal of the arithmetic square root of the sample size, and the larger the calculation sample size is, the smaller the relative errors of the standard values of the stable ultimately bearing capabilities of the structures are.
