Maintenance Frequency Optimization of Corroded Reinforced Concrete Structures Based on Reliability Theory

Corroded structure corrosion rates vary with different environments. Maintenance is required to meet the service life. It is an urgent problem to confirm maintenance frequency for corroded structures. Dynamic reliability of multiple maintenance for corroded reinforced concrete structures was studied. The method of optimal maintenance number is also put forward for corroded reinforced concrete structures under the condition of reinforcement.
