Examples
- It is the researchful purpose of this paper that the methods of appraising the existing structural reliability basing on own information are found , which will impel the methods of appraising the existing structural develop from applied methods to probability methods . the contents of this paper have mainly four , including : firstly , the normal value of permanent load in the existing structure is ascertained by the way that is called bayes - small capacity , which considers the dates of design and the road - test dates . secondly , by introducing the random variable that is statistical ambiguity , the statistics of loading and resistance of existing structure are researched
本文研究目的是针对现有结构的特点，建立基于自身信息的现有结构可靠性的实用评定方法，推动我国的现有结构可靠性鉴定方法由实用鉴定法向概率鉴定法发展，主要研究内容包括四个方面：一、结合结构原设计数据和现场抽样实测数据，研究了恒载标准值的统计推断方法，提出bayes小样本统计推断方法；二、利用统计不定性随机变量，结合现有结构的特点，提出荷载、抗力变异性的小样本统计推断方法；三、分析了现有结构抗力变异性的主要影响因素，并利用实测数据进行了实例分析；四、针对现有结构自身的荷载、抗力统计特性，研究了现有结构承载力的校核表达式，对恒载、抗力分项系数提出修订建议，建立了基于自身信息的现有结构可靠性实用评定方法。
