| 摘 要： | 利用贝叶斯方法对既有结构当前的抗力标准值进行推断,原理是假定无信息先验分布,并用样本信息修正先验信息,然后进行统计推断得到后验信息.文章提出了变异系数未知和已知情况下抗力标准值的贝叶斯推断公式,并予以验证.

| Abstract: | The paper makes use of the bayes method to carry on prediction to the current resistance characteristic value of existing structure.The principle is supposed that prior distribute is without the information.Then it carries on a statistic prediction and gets a posterior information by using sample information to check the prior information.In this paper,the bayes predict formula of the resistance characteristic value is put forward in the condition of the coefficient of variation is known or unknown,and an a... |
