Structural Assessment of corroded reinforced concrete plates

The corrosion of steel in reinforced concrete elements exposed to maritime and ocean harsh environment conditions is dependent on the rate of chloride penetration to the steel, the resistivity of the concrete and the oxygen diffusion through the cover regions. Reinforcement corrosion may result in spalling of the concrete depending on factors such as the thickness of the cover and the strength of the concrete. Concrete plate and
shell panels represent the most predominant structural element used in marine structures and the walls of concrete offshore platforms. In this project, the experimental phase starts by casting two control plates as a reference. Another two plates will then be cast and the reinforcement will be corroded. The second phase involves creating finite element models based on the obtained experimental results. The models will be used to simulate the structural behaviour, deflection and cracking of RC plates under corroded reinforcement and certain corroded area. The proposed research project will be relevant to SNC and their involvement in the marine and off shore industry. In the partners various projects there is a need to develop expertise and innovative solutions to facilitate the construction and rehabilitation of sustainable concrete marine infrastructure.
