The structure defection analysis and the reinforcing technology to the reinforced concrete bridge;

Research on durability assessment for reinforced concrete bridge;

The durability of reinforced concrete bridge;

Study on the causes of insufficient durability of RC bridge and countermeasures;

Date of domestic and international show that the economic loss caused of the harms of enduring disease of the bridge structure is very huge, and along with variety of environment, growth of service time , raise of function request, The durability problem of in service RC bridge is more and more outstanding.

State-of-art of the mechanical behaviour of the corrosion reinforced concrete bridges;

With the rapid development of transport routes,it is important to find out whether the bridge can meet the heavy cargo transport development and take on the needs of large equipment transport tasks, as well as after the passage of overloading of vehicles how much will fatigue properties change on the existing reinforced concrete bridges, which are issues of concern to the urgent need .

Recently,the deterioration and damage of reinforced concrete bridges caused by durability inadequate were more and more serious and widespread,the normal use or security operations of the bridges were seriously affect,and the economic losses far beyond people\'s imagination.

The ultimate frequency can be taken as an important criterion for evaluating RC beam bridge load capacity.
