Abstract: The objective of this study is to establish a computational system that can evaluate structural petformances exposed to various environmentaVweather actions. In this study, equilibriurn, adsorption/desorption, and transport phenomena of gas and ion, and corrosion of reinforcing
bars in concrete are formulated based on thermodynamics and electrochemistry. The core of these formulations is based on thermodynamic couplings of moisture transport, powder material hydration and the microstructure formation phenomenon's with very few assumed functional relationships. Preliminary simulation studies related to chloride transport, carbonation and corrosion show the versatility and extensibility of the proposed schemes.
