dc.description.abstractThere is still a disconnection between the structural and nonstructural components in the analysis and design stages of healthcare facilities, and consequently, the earthquake-induced nonstructural damage is still causing loss of functionality despite the negligible building’s structural damage. Aiming to bridge this disconnection, the present research focuses on the development of probabilistic damage scenarios of hospital critical rooms taking into account the structural, nonstructural, and content interaction simultaneously. To achieve this goal, an Emergency Room (ER), an Intensive Care Unit (ICU), and an Operating Room (OR) are simulated fully equipped at the first, fourth, and fifth levels of a mid-rise hospital building, developed in OpenSees, and subjected to the Service (SE), Design (DE), and Maximum Considered Earthquake (MCE) levels, considering Fixed-to-the-Base (FB) and Base-Isolated (BI) support conditions. The building’s floor responses are then used as input motions to assess the performance of different Nonstructural elements, Systems, and Contents NSCs arranged at each critical room. Then, fragility analyses, using IDA, are conducted to obtain the structural, nonstructural, and medical content fragility curves. Finally, probabilistic damage scenarios are constructed by coupling structural-nonstructural-content fragilities using the Performance-Based Earthquake Engineering methodology via Monte Carlo Simulations. Results highlight the benefits of base isolation in remarkably reducing structural, nonstructural, and content damage within hospital critical rooms for all earthquake hazard levels. Moreover, it was found that solely preventing structural damage is not enough to ensure the continuity in the provision of medical services. Finally, the urgent need to develop code-based performance objectives for NSC for low-, moderate-, and design-level earthquake motions was quantitatively and qualitatively demonstrated.
