“…The strengthening and stiffening strategy is essentially based on the addition of shear walls, bracings and vertical frames within the building’s bays. The effects of adding steel bracings was experimentally tested in [11][12]. In the latter, the tests results were compared with those from nonlinear time history analyses of a building’s prototype with bracings.…”

A project named PERSISTAH ( Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva , in Portuguese) is being developed. It aims to cooperatively assess and improve the seismic vulnerability of primary schools in the Algarve (Portugal) and Huelva (Spain). A large number of schools have to be analysed. In order to determine which seismic retrofitting technique is optimal, an index-based method is presented in this paper. It considers three parameters: first, the efficiency of the seismic retrofitting technique in relation to the structural improvement obtained; second, the cost of the implementation of the retrofitting technique; and third, the architectural impact. It should be mentioned that a specific measurement for each solution according to its geometry has been performed. Also, coefficients to consider the singularities of each analysis and the importance of the parameters (number of buildings, typology, available funds, etc.) in the study are considered. The most representative primary school of Huelva has been chosen to test the index-based method. The most suitable retrofitting techniques for this type of buildings have been tested. The retrofitting technique which most increased the seismic performance has been the addition of X and V bracings within the building’s bays. Furthermore, the analyses have revealed that adding the retrofitting elements in the most vulnerable direction of the building provides a high efficiency. The results have also shown that implementing techniques of lower architectural impact gives acceptable results. The analysis of the mean damage level index has shown that the building would experiment a severe damage. All the retrofitting techniques applied have reduced it, at least, up to moderate damage. Finally, it should be noted that the position of the retrofitting elements is also paramount for providing an optimal retrofitting.

“…The behaviour of structures in which steel braces were incorporated was analysed experimentally in (TahamouliRoudsari et al, 2017;Ozcelik et al, 2012). In (Ozcelik et al, 2012), a comparison was made between the improvement produced by shear walls and steel bracing, respectively.…”

The present book aims to present the work developed in the European research project PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese), which has been developed cooperatively by the University of Seville (Spain) and the University of the Algarve (Portugal). This research project focuses on the study and assessment of the seismic risk of primary education buildings in the territory of the Algarve (Portugal) and Huelva (Spain). To this end, the objectives established by the National Platforms for Disaster Risk Reduction (PNRRC) of the National Civil Protection Commissions of Portugal and Spain have been taken into account.
