| Abstract | Seismic risk is a key factor influencing several important decision-making processes from performance-based design of new structures, to investments for rehabilitation of existing buildings and even to seismic mitigation campaigns of large building stocks. In order to evaluate the economic convenience of alternative mitigation strategies the expected seismic losses for different solutions (including the “do nothing”) in a given timeframe should be compared. The PEER performance-based earthquake engineering framework is normally adopted in order to compute losses. However, its application with a number of Non-linear Response History analyses as a basis for assessment of expected Engineering Demand Parameters and associated losses is an elaborate and time-consuming task, hardly employable for the assessment of earthquake losses for large building portfolios. This paper tests the applicability of a simplified pushover based approach for computation of earthquake losses. Referring to a case study building the results of application of classical PEER approach, i.e. based on Non-linear Response History analyses, are compared with the losses computed with pushover-based assessment, showing encouraging results. In addition, the simplified approach is used to investigate the effect of alternative retrofit strategies on the variation of expected seismic losses. 2805 Available online at www.eccomasproceedia.org Eccomas Proceedia COMPDYN (2017) 2805-2822 © 2017 The Authors.
