| Abstract: | The effects of fiduciary level, strength coefficient and stress coefficient were analysed on three reliability safety coefficients. The relative errors of the three safety coefficients were compared, and the respective applicable conditions of them were discussed. The correction of the conclusions given is illustrated by an example. |
