Abstract


Coefficient of variation is relative non-dimensional volume,which reflect the risk and uncertainty of structure.It is more scientific,and more practical to apply to the dependence of the Structure,but in the practical problem it is very hard to get the available data of the structure,so we only research the dependence of the Structure with the small sample.the article will study the problem of coefficient of variation using in the test under the situation of the small sample.It will bring important significance.First,The article introduced the concept of coefficient of variation and significance, gives theory of the reliability of structures and h distribution with coefficient of variation,and some of it’s property.then use the Matlab establishing the probability distribution table of sampling distribution with coefficient of variation and discuss the hypothesis test of coefficient of variation.the article use a frondose example to realize the evaluation of the reliability on the structure,the result coincide with the practical situation,prove it’s application.The aticle utilize h distribution to process the hypothesis test of coefficient of variation and apply to the reliability of structures.it will promote the evaluation of reliability of structures.meanwhile it also can be applied to the reliability of other domanial.
