| Abstract: | Some problems about to known variation coefficients of strength and load were presented in this pa-per,those are:(1)the engineering background.(2)the deriving probability distribution of quotient of normal dis-tribution.(3)the improving research results.41 the analysis method for confidence inferior limit of structural re-liability,and equal probability curve of quotient distribution,Comparing of various reliability evaluation methodsby example,it may be seen that the method presented in the paper has been of superiority and practicality,and thedata of variation coefficient have been of importance to structural reliability analysis. |
