| 摘 要： | 高强度混凝土梁梁在剪力作用下裂缝的形成,扩展和分布十分复杂,本文借助模型实验获得了高强混凝土深梁在剪力作用下的裂缝分布规律,应用分形几何理论研究了裂缝分布的自相似性。研究表明,所形成的裂缝有很好的自相似性,分形维数可描述裂隙化程度,且剪力,挠度与分形维数具有明显的量化关系。

| Abstract: | Cracks form, extension, distributing of High-Strength Concrete Beams is complex under shearing force. By using fractal geometry, the distribution of crack is examined. It is found that the crack exhibits good self-similarity, and its fractal dimension can be used to describe the degree of developing in crack. It is also found that there exists a relationship between shearing force, deflection and the fractal dimension. |
