| Abstract: | The performance of reinforced concrete structures exposed in aggresive environment deteriorates as a result of attack of environmental stressor. In this paper, the reliability of reinforced concrete structures under corrosion attack is calculated. The influence of environmental condition, concrete strength and concrete cover on structural reliability is investigated. The results indicate that the reliability of reinforced concrete structures exposed in aggresive environment is strongly affected by concrete strength and concrete cover. So the design of durability of reinforced concrete structures is of great importance in aggresive atmospheric environment. |
