摘要
将混凝土剪压（包括剪拉）强度相关性规律统一表达为三参数椭圆公式或两参数椭圆公式其中，三参数椭圆公式符合某些试验结果：而两参数椭圆公式，或是由三参数椭圆公式简化而来，或是由双参数强度准则导出的，将它们分别与试验公式作了比较。
An elliptic formula with three parameters or an elliptic formula with two parameters expresses the law of the relationship between shear strength and compressive(or tensile) strength of concrete The elliptic formula with three parameters is in good correspondence with same test results The elliptic fomula with two parameters is from simplifying the elliptic formula with three parameters of from a strength theory with two parameters and is compared with some test results Two of the elliptic formulas with two parameters are available
