【摘要】 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。更多还原

【Abstract】 The natural frequency of corroded reinforced concrete structures are simulated by finite element method. The change of the natural frequency of the reinforced concrete structure under the different degree of corrosion was discussed. The results show that the corrosion of reinforced concrete has a significant effect on the natural frequency of reinforced concrete beams,and the natural frequency decreases with the depth of corrosion.更多还原
