INTRODUCTION: During and after an earthquake, damage to operational and functional components (OFCs) is a major concern. OFCs are mostly non-structural elements of a building that make it work. The HVAC system of a high-rise makes it inhabitable. The suspended ceiling in an office hides the mechanical and electrical systems behind it. The sculpture in a building lobby adds to the aesthetics of the environment. In 2004, a major study identified an earthquake as the worst potential natural disaster threatening Canada (Etkin et al, 2004). Eastern Canada has seen it’s fair share of large earthquakes. In 1988 a magnitude 6.0 (on the Richter scale) earthquake in Saguenay caused major damage to masonry cladding of Montréal-Est city hall. In 1929 a magnitude 7.2 earthquake caused a tsunami that affected most of the eastern seaboard.

OBJECTIVE: As part of the CSRN and in collaboration with the Centre de Sécurité Civil de Montréal (CSC), our project aimed to evaluate the seismic vulnerability of OFCs in Montreal emergency shelters and fire stations. This was done by qualitative inspection and application of special seismic restraint standards. With this information, the CSC will have a better idea of how these buildings will fare during and after a major earthquake in order to better prepare the city for such an event. Also, the CSRN will know where to focus mitigation strategies in later stages of the research process.

To address this threat, researchers, industry and policy makers from across Canada formed the Canadian Seismic Research Network (CSRN)
