Abstract
The corrosion of structural steel will enable the degradation on performance of reinforced concrete structures,which also has a certain impact on the dynamic characteristics of the structures.The natural frequencies of corroded reinforced concrete frame structures are simulated by finite element method,and the changes of the natural frequencies of the reinforced concrete structure in different states of corrosion damage are discussed.Results from above find that the changes of the natural frequencies of the reinforced concrete structures are not only related to the corrosion degree of reinforced steel but also to the location of corrosion.
