The Research of Concrete Durability Design Xuesong Zhang a, Jinping Chen b Colledge of Pipeline and Civil Engineering, China University of Petroleum Qingdao, Shandong, 266555, China asnowpiner@upc.edu.cn, bchenjp@upc.edu.cn Keywords: Reinforced Concrete Structure, Durability design system; Damage control Abstract.
Therefore, the track monitor and the durability re-engineering should be carried on in the service structure.
To realize the concrete structure durability design has become the significant theory and the project question that is urgently needed to be solved of the structural engineering.
Therefore in the reality engineering design and the fundamental research, unceasing development and the consummation must be given to the system.
