| 摘 要： | 本文从试验现象出发,建立了以数理统计为基础的混凝土受拉全过程曲线方程。研究表明,混凝土受拉应力应变全曲线是混凝土试件内部的粘结界面与水泥胶合物在外拉力作用下逐步断裂造成的。文章所建立的方法不仅可以解释许多试验现象,模拟混凝土受拉全曲线,而且还可以得出试验中难以测出的结果。

| Abstract: | Based on the experiment, the tensile strain-stress relationship
was set up by means of the stochastic theory. Researches proved that the complete curve for concrete under tension was caused by the gradually fracturing of bond and cementitions colloids during loading. It was also proved that the method proposed in this paper can be applied not only to explain many test results and to determine the tensile complete curve for concrete under tension, but also to obtain some results which are difficult to get from test |
