One of the advantages of reinforced concrete (RC) structures is its durability. However, when they are exposed to aggressive environments (e.g., chloride penetration) and cyclic loading, its performance can be significantly affected. Modeling deterioration produced by chloride penetration is useful to ensure optimal levels of serviceability and safety. The main purpose of this book is to propose a new model for lifetime assessment of RC structures subjected to deterioration produced by the combined action of corrosion and fatigue. The formulation of the model is based on a state of the art review on modeling of this kind of deterioration. Furthermore, taking into account the importance of the uncertainty related to the whole deterioration process, this book also presents a stochastic framework for this problem. Finally, several practical examples illustrate the effects of the corrosion-fatigue process in the reduction of life-cycle of RC structures.
