| Resumo: | A significant part of the Portuguese building stock was not designed considering seismic provisions. As such, the recent growth of the building rehabilitation sector may represent a unique opportunity to reduce the seismic vulnerability of existing buildings, and consequently the associated earthquake risk. In this context, the present work presents a methodology to evaluate the seismic vulnerability of a class of reinforced concrete buildings and allows the definition of simplified indicators representing their expected structural performance. The proposed methodology is based on a detailed numerical study of the seismic behaviour of reinforced concrete buildings with representative characteristics of a significant part of the Portuguese building stock that adequately simulates the main aspects of the buildings' structural response. The results obtained by the methodology highlight the main vulnerabilities of the chosen building class and enable the quantification of structural performance indicators that can be used for the simplified structural safety assessment of similar structures. |
