Seismic vulnerability of a high-rise hospital building using field monitoring data
Sotiria Karapetrou, Dimitris Pitilakis
Abstract:
In this study, the seismic vulnerability of a high-rise hospital building is evaluated, combining numerical analysis and field monitoring data. The target building is an eight-storey reinforced concrete (RC) structure composed by two units separated through a structural joint. The assessment of the dynamic characteristics is performed using ambient noise measurements recorded by a temporary seismic network deployed inside the hospital. The modal identification results are used to update and better constrain the initial finite element model of the building, which is based on the available design and construction documentation plans. Three-dimensional incremental dynamic analysis is performed to derive the fragility curves for the initial as built model and for the real structures as they are nowadays. Results indicate that the consideration of the actual state of structures may significantly alter their expected seismic performance leading to higher vulnerability values.
