利用有限元软件ANSYS,对发生钢筋锈蚀后的钢筋混凝土结构进行了数值模拟,探讨了在钢筋不同锈蚀程度的情况下,钢筋混凝土结构固有频率的变化情况,模拟结果表明,钢筋锈蚀对钢筋混凝土梁的固有频率有显著影响,钢筋混凝土梁的固有频率随着钢筋锈蚀程度的加深而呈减小趋势。
The finite element software ANSYS was used to simulate the steel reinforced concrete structure after corrosion of steel bar. The change of natural frequency of reinforced concrete structure under different corrosion degree of steel bar was discussed. The simulation results show that the corrosion of steel bar reinforced concrete The natural frequency has a significant impact, the natural frequency of reinforced concrete beams with the deepening of corrosion of steel tend to decrease.
