摘要
传统上认为混凝土强度分布是服从正态分布,主要是考虑到函数的简单化。本文作者以复合材料的观点分析混凝土的破坏机理,并运用强度的统计理论,分析了混凝土单轴受压破坏的概率模型,认为研究混凝土单轴受压破坏宜采用最弱环模型,其强度服从三参数Weibull分布,并得到试验验证。本文作者还给出了具有置信度的混凝土强度可靠度的计算方法。
According to the principle of probability and statistics,the mechanisms of concrete damage and the characteristic of three-parameter Weibull distribution are studies,and statistical model of concrete strength is established in this paper.In the base of the academic analyses and test,a statistic model of concrete strength,based the weakest chain theory,is put forward,and three-parameter Weibull distribution to describe its distributing rule is used to consequently study the concrete strength.Accordingly,the livability of the strength in the specified confidence can be got.
