Probabilistic Design for the Durability of Reinforced Concrete Structural Elements Exposed to Chloride Containing Environments

Abstract

To obtain structures with long service lives in chloride containing environments, durability design methods should be carried out. In such a design, chloride diffusion must be expressed as a mathematical model and the parameters should be included in this model in a realistic way. The scatter both in the environmental exposure conditions and structural properties should be considered with a probabilistic design. The main objective of this study is the durability design of concrete structures in chloride containing environments. The transport of chlorides into concrete was modeled using Fick’s second law of diffusion and a simple software based on Monte Carlo simulation was developed to consider the scatter in the environmental exposure conditions and structural properties. The effects of some important structural parameters affecting corrosion were investigated.
