Abstract(s)
As recentes catástrofes provocadas pelos sismos de L’Aquila, do Haiti e do Chile vieram
relembrar a importância do reforço sísmico de estruturas situadas em l ocais de risco sísmico
elevado.
As unidades de saúde são das estruturas em que mais importância tem a operacionalidade
imediatamente após a ocorrência de um sismo, sendo fundamental que se concebam planos
para o reforço sísmico deste tipo de estruturas, que englobem os recentes desenvolvimentos nesta área, de forma a salvaguardar o parque hospitalar, em caso de sismo.
O primeiro passo para o reforço estrutural passa por um rastreio das unidades em que é
mais urgente este reforço. Para tal, face ao universo bastante alargado de estruturas que prestam cuidados de saúde, é necessário desenvolver métodos expeditos, que permitam uma primeira hierarquização de estruturas em que é mais premente a intervenção. É com este objectivo que tem vindo a ser desenvolvida uma metodologia de avaliação do risco sísmico, baseada num conjunto de normas japonesas. Pode considerar-se que esta metodologia apresenta uma complexidade e um rigor intermédios, entre as metodologias ditas generalizadas, que se baseiam só em factores como o número de pisos, a localização do edifício, o material estrutural, etc. e as que recorrem a meios computacionais avançados como as análises estáticas não lineares.
Nesta dissertação apresenta-se a metodologia ICIST/ACSS, procedendo à sua aplicação ao
centro de saúde de Loulé. Recorreu-se a processos mais elaborados para aferir o rigor da metodologia em análise. Retirando daqui conclusões que se espera que contribuam, de futuro, para uma melhor calibração do método.
Abstract The recent catastrophes caused by the earthquakes in L’Aquila, in Haiti and in Chile came as a reminder of the importance of seismic retrofit of structures located in high seismic hazard zones. Health units are the prime examples of structures that should be operational immediately after an earthquake. It’s of the utmost importance to conceive plans in order to proceed with the seismic retrofit of this kind of structures, based on the most recent developments in this area, in order to safeguard hospital facilities, in the event of an earthquake. The first step towards seismic retrofitting is to scan units in order to identify those where retrofitting is more urgent. To be able to achieve this goal it’s necessary to develop a quick method that allows a first hierarchization of structures where intervention is more pressing. Keeping this in mind, it has been developed a methodology of evaluation of the seismic hazard based on a Japanese standard. It’s considered that this methodology presents an intermediate complexity and rigour between those based only on factors such as the number of storeys, the building’s location, the structural material, etc. and those that require more advances computational means as non-linear static analysis. In this dissertation it’s present the ICIST/ACSS methodology, applying it to the Loulé Health Centre. More elaborated processes were used to evaluate the rigour of the analysed methodology. Conclusions were withdrawn and it’s hoped that they will, in the future, contribute for a better calibration of the method.
