摘要
根据有关标准更新换代前后相关规定的变化和已有的研究成果,分析得到轻骨料混凝土轴心抗压强度、轴心抗拉强度与立方体抗压强度之间的换算关系。根据构件材性随机变量κC的概率密度函数的数学模型,按照随机变量函数统计参数的运算法则,得出轻骨料混凝土强度的统计参数。基于该统计参数和材料强度标准值的定义,得出轻骨料混凝土轴心抗压强度和轴心抗拉强度的标准值。
Based on the analysis of the changes in the pertinent regulations of the standards concerned and the existing experimeutal results, the conversion relations between axial compressive strength and cubic compressive strength; between direct tensile strength and cubic compressive strength of lightweight aggregate concrete were deduced. According to the mathematical model of probability density function of random variable x~, the statistical parameters of the strength of lightweight aggregate concrete were obtained in the light of computation rules of the statistical parameter of random variable function. On the basis of the statistical parameters and the definition of characteristic value of material strength, the standard values of axial compressive strength and direct tensile strength of lightweight aggregate concrete were acquired
