Damage and loss evaluation in the performance-based wind engineering

Aim of this paper is to investigate the role of damage and loss analysis in the PBWE. Starting from a comprehensive literature review on the topic in other fields, and on the basis of critical analysis and synthesis, a conceptual framework is presented, not only for safety, but also for the serviceability assessment of structures under wind loads. First, appropriate criteria need to be defined in order to characterize the uncertainty affecting the response thresholds assumed for the evaluation of the serviceability levels. This is particularly difficult in the evaluation of the building residents comfort. Second, the monetary quantification of the loss of serviceability is required. In the authors' knowledge this aspect is, at the moment, poorly treated in the literature on tall building serviceability under wind action. © 2013 Taylor & Francis Group, London.
