The impact of environmental conditions of Persian Gulf on the probability of chloride corrosion initiation in reinforced concrete structures

According to the technical literature, the amount of chloride that is transported by air from the sea surface depends on the amount of salt in the seawater in that area, the speed and direction of the wind, and the distance from the sea. Accordingly, data on the highest annual wind speed and direction of the wind are collected in several reinforced concrete structures (RC structures) in southern cities near the Persian Gulf at different distances from the sea. In this paper, by applying probabilistic modeling and utilizing the Hasofer–Lind and Rackwitz–Fiessler (HL-RF) method of reliability by aligning the enhanced Colliding Bodies Optimization method (ECBO) algorithm, and utilizing the data from the National Meteorological Organization, for concrete structures located in different distances with different speeds and directions of the wind from the Persian Gulf, the time of chloride corrosion initiation in reinforced concrete structures and the durability of these structures has been surveyed.
