本文根据大量实测数据,依据统计数学提供的方法进行分析,提出了钢筋混凝土结构构件几何尺寸变量的主要统计参数,研究了其概率分布形式,为研究钢筋混凝土结构构件的可靠度提供了分析依据,本文还根据统计分析的结果,对我国现行的国家标准(TJ 321-76)中有关构件几何尺寸允许偏差值的规定进行了对比分析,并对我国当前钢筋混凝土结构构件几何尺寸的实际质量水平作出了评价。
In this paper, based on a large number of measured data, according to the methods provided by statistical mathematics analysis, the main statistical parameters of the geometric dimension variables of reinforced concrete structural members are proposed, and the probability distribution form is studied, which provides an analysis basis for the study of the reliability of reinforced concrete structural members. Based on the results of statistical analysis, this article also makes a comparative analysis of the provisions of the current national standards (TJ 321-76) on the allowable deviation of the geometric dimensions of the components, and makes the actual quality level of the current geometric dimensions of the reinforced concrete structural components in China. Evaluation.
