The corrosion process in reinforced concrete structures, exposed to marine or industrial environments, causes the appearance and growth of cracks. As a consequence, this produces a slow degradation of the material physical properties, steel fragilization and a decrease of the bond strength and steel reinforcements, cross section, affecting its static and dynamic behavior.In the second half of the twentieth century, the importance of constructions' service life was noticed, so different techniques have been developed to predict the Residual Life of existing structures, in order to increase it. This situation has a significant economic impact on society.This paper presents a non-destructive technique to predict the Residual Life of reinforced concrete beams having different cracking levels, as results of steel reinforcement corrosion, considering the variation produced in the dynamic behavior, through the variation of the first natural vibration frequency.The reinforcement corrosion is an electrochemical process that can be quantified by measuring the intensity of the current on the concrete surface. In this paper, to simulate the corrosion process, a current is externally applied to the studied structure reinforcement and then crack widths and vibration natural frequencies are measured. Based on these measurements a mathematical model is proposed to predict structure remaining life. ª 2014 Production and hosting by Elsevier B.V. on behalf of Housing and Building National Research Center.

Robustness is considered as an attribute of a structural system that relates to its ability to fulfil its function in the face of adverse events. It is difficult to quantify robustness. The focus of COST action TU0601 has been on developing a framework to quantify robustness and on identifying methods and strategies to improve the robustness of structures. The objectives of this paper are to present an analysis of different failures from the point of view of robustness and to identify measures that directly or indirectly contribute to robustness. It is concluded that structural form plays a major role but it is essential to ensure good management processes for design and construction.

Risk assessment is a requirement for robustness design of high consequence class structures, yet very little guidance is offered in practice for performing this type of assessment. This paper demonstrates the application of the probabilistic risk assessment framework arising from COST Action TU0601 to multi-storey buildings subject to extr eme loading. A brief outline of the probabilistic framework is first provided, including the main requirements of describi ng uncertainty in the hazards and the associated local damage as wel l as the consequences of global failure. From a practical application perspectiv e, it is emphasised that there is a need for (a) computationally efficient deterministic models of global failure for specific local damage scenarios, and (b) effective probabilistic simulation methods that can establish the conditional probability of global failure on local damage. In this respect, this work utilises a recently developed multi-level deterministic assessment framework for multi-storey buildings subject to sudden column loss, which is coupled with a response surface approach utilising firstorder reliability methods to establish the conditional probability of failure. The application of the proposed approach is illustrated to a multi-storey steelcomposite building, where it is demonstrated that probabilistic risk assessment is a practical prospe ct. The paper concludes with a critical appraisal of probabilistic risk assessment, highlighting areas of future improvement.
