Seismic fragility analysis of concrete dams: A state-of-the-art review

Dams are critical infra-structures whose their failure could leads to high economic and social consequences. For this reason, application of quantitative risk analysis has gained extensive attention in recent years. Dam safety management has become an indispensable part of all dam engineering projects worldwide. The concept of risk is heavily tied to probabilistic methods. From an engineering point of view, a clear definition of the terminologies involved in dam safety, and a comprehensive state-of-the-art review of the current literature are the starting points towards an effective risk-based approach. The first part of this paper provides a systematic review on the fundamental elements in uncertainty quantification. Then, different terminologies in risk-based dam safety are explored and their inter-connections are discussed. More than 350 papers are summarized, and several tables and conceptual plots are used for extra clarification. Since no such a paper is ever published, hopefully this can unify all the future activities and improves our understanding from probabilistic risk analysis.

Probabilistic finite element analysis of concrete gravity dams

Probabilistic analysis of reinforced concrete columns

Usually, reinforced concrete design codes indicate only one simplified method for second order analysis of slender columns. The Eurocode 2 (EC2), on the other hand, adopts two simplified methods: one based on nominal stiffness and other based on nominal curvature. It would be desirable that both methods could provide similar solutions. However, this is not the case, as shown in this paper. On the contrary, the two EC2 simplified methods can provide very different results, leaving the engineer uncertain about which method he should use. The objective of this work is to compare these two simplified methods presenting the contradictions between them. Several experimental results available in the literature have been analysed and compared. The method based on the nominal curvature showed to be the most accurate; therefore, it is suggested to be used.
