摘要
在12组三点弯曲梁稳定断裂试验的基础上,采用逆分析法获得混凝土四线性软化曲线,系统地研究了骨料粒径、试件尺寸,混凝土强度等对混凝土软化特性的影响规律.
On the basis of 12 groups of experiments on the stable fracture of three-point bending beams, four-linear softening curves of concrete were obtained with the inverse analysis method. A systematic study was conducted to investigate into the effects of the aggregate size, specimen size and concrete strength on the softening properties of concrete.
