“…Some of the literature only analyzed the one-dimensional chloride diffusion [15], and some did not take into account the effects of the denaturation of the parameters [4]. At the level of structure, many concrete structures are eroded by the chloride in two or even multiple directions for the actual concrete structures [14], such as beam-column members [6]- [9] and cracked concrete structures [10]- [11]. The results of experimental tests [12] and numerical model studies [13] have shown that the chloride concentration in two-dimensional diffusion regions is higher than that in the one-dimensional diffusion regions.…”

In this paper, the age factor of chloride diffusion coefficient of concrete is considered, as well as the randomness of the chloride diffusion coefficient, concrete cover depth, surface concentration, threshold concentration and age factor. Based on the First Order Reliability Method, a time-dependent reliability analysis model for concrete structures under chloride conditions is established. The results show that the time-dependent reliability model is in good agreement with the Monte Carlo sampling method. The results of example show that the corner region of the concrete structure must be designed and calculated based on the two-dimensional diffusion model, and the attenuation characteristics and randomness must be considered for the concrete structures in chloride environment.
