摘要
采用三维有限元分析软件LS-DYNA建立水工环境下锈蚀钢纤维混凝土梁数值模型,针对水工环境下锈蚀钢纤维混凝土梁抗冲击性能进行研究,分析考虑不同锈蚀率和冲击能量等参数对锈蚀钢筋混凝土梁的抗冲撞性能的影响,探讨了锈蚀钢纤维混凝土梁力学性能退化规律。
The article is based on the three-dimensional finite element analysis software LS-DYNA to establish the numerical model of corroded steel fiber concrete beam in hydraulic environment and studied the impact resistance of corroded steel fiber concrete beam in hydraulic environment. At the same time, the corrosion resistance and impact energy are considered, the influence of the impact resistance of reinforced concrete beams on the mechanical properties of corroded steel fiber reinforced concrete beams is discussed.
