摘要
针对混凝土直接拉伸试验得到的混凝土轴心抗拉强度的试验数据进行分析,研究试件尺寸与粉煤灰对混凝土轴心抗拉强度与立方体抗压强度关系的影响,并给出建议计算式。通过试验数据回归分析,提出了混凝土轴心抗拉强度与混凝土立方体抗压强度的换算关系,并与国内外几种主要混凝土结构设计规范的相关建议计算式进行了比较。
The paper analyzed axial tensile strength test data of fly ash concrete, which was obtained by direct tensile tests with different dimensions and concrete grades. The effect of specimen dimensions and fly-ash on the relationship between axial tensile strength and cubic compressive strength were studied , and the recommended formula was proposed. Through the experimental data regression analysis, the conversion relationship between axial tensile strength and cubic compressive strength of concrete was put forward and compared with related recommended formulas of several major codes for design of concrete structures at home and abroad.
