The latent failure probability: A conceptual basis for robust, reliability-based and risk-based design optimization Open
The safety of structural systems depends on social, political, financial, organizational, behavioral, and other non-structural factors. These factors are related to use of the structure and its environment, malevolent and other unanticipat…

Reliability analysis of reinforced concrete frames subjected to post-construction settlements Open
Most papers in the literature address reliability analysis of isolated elements, like beams and columns. However, symmetry and regularity are often exploited in the construction of regular RC frames, resulting in the same or similar design…
