Abstract: Adding steel fiber to traditional concrete improves its tension strength and crack resistance to a great extent.By the meso-mechanical analysis presented in the paper, it reveals that the fiber's physical properties, geometrical conditions and the interficial bonding state have a marked effect on the macroscopic tension behavior of the composite.Theoretical formula of the tension proportional limit derived here gives a good agreement to the testing results.
Key words: steel fiber reinforced concrete, meso-mechanics tension proportional limit, interficial damage, meso-mechanical analysis
摘要： 对纤维体积掺量和长径比>80的钢纤维砼进行了细观力学分析,实验与分析结果表明:钢纤维的物理性质、几何参数分布形式以及与砼基体之间的界面粘结状态对钢纤维砼的宏观拉伸行为有着重要影响.由此导得的抗拉比例极限公式与试验结果吻合良好.
关键词: 钢纤维混凝土, 抗拉比例极限, 界面损伤, 细观力学分析
