2.2. Structural Performance, Ground Settlement, and Acceleration Mitigation
Applying a systematic decision framework to healthcare infrastructure demonstrates that structural retrofit prioritization must balance geotechnical stabilization, drift control, and operational continuity. According to established prioritization methodologies, technical interventions are classified by weighing structural vulnerability against service criticality to optimize resource allocation across complex building portfolios (Seismic repair and retrofit prioritization framework, 2022). In strategic public complexes, superstructure reinforcement alone cannot guarantee operational resilience if foundation subgrades remain susceptible to differential settlement, underscoring the critical need to integrate ground improvement works with structural retrofitting (Christchurch Town Hall Complex: Post-Earthquake Ground Improvement, Structural Repair, and Seismic Retrofit, 2020). Moreover, analysis of occupied reinforced concrete facilities indicates that seismic isolation techniques drastically reduce floor accelerations and inter-story drift while permitting ongoing building occupancy during construction (Seismic Retrofit of R.C. Buildings in Use Through Seismic Isolation, 2023). When applied to hospital facilities, base isolation mitigates the dynamic forces that damage essential non-structural medical systems, clinical equipment, and MEP installations. Integrating geotechnical reliability, acceleration mitigation through base isolation, and operational constraints into the analytical model confirms that retrofit sequencing for acute healthcare infrastructure must prioritize immediate post-earthquake functional recovery rather than conventional life-safety performance objectives.
