ABSTRACT
The Iberian Peninsula is close to the Eurasia-Africa plate boundary
resulting in a considerable seismic hazard. In fact, the southwestern Iberian
Peninsula is affected by far away earthquakes of long-return period with
large-very large magnitude. A project named PERSISTAH (Projetos de Escolas
Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese)
aims to cooperatively assess the seismic vulnerability of primary schools
located in the Algarve (Portugal) and Huelva (Spain). Primary schools have been
selected due to the considerable amount of similar buildings and their seismic
vulnerability. In Portugal, the Decreto Lei 235/83 (RSAEEP) is mandatory while
in Spain, the mandatory code is the Seismic Building Code (NCSE-02). In both
countries, the Eurocode-8 (EC-8) is recommended. Despite the fact that both
regions would be equally affected by an earthquake, both seismic codes are significantly
different. This research compares the seismic action of Ayamonte (Huelva) and
Vila Real de Santo António (Portugal). Both towns are very close and located at
both sides of the border. Moreover, they share the same geology. This analysis
has been applied considering a reinforced
concrete (RC) primary school
building located in Huelva. To do so, the performance-based method has been
used. The seismic action and the damage levels are compared and analysed. The
results have shown considerable differences in the seismic actions designation,
in the performance point values and in the damage levels. The values considered
in the Portuguese code are significantly more unfavourable. An agreement
between codes should be made for border regions.
