This paper presents an analysis method of mechanical behavior of aged concrete structures on elastic theory, and analyses the main causes of load bearing performance of concrete structures. the paper also illustrates some studies where structures exposed to the marine environment showed early deterioration and analyses the main causes of structural concrete deterioration, including concrete carbonization, corrosion mechanisms of concrete, and mechanisms of steel corrosion due to the penetration of chloride ions into the concrete. it shows that corrosion of the reinforcements is the main cause of structural concrete deterioration
