When the shadow of disaster looms over the land, hospitals and schools often become people’s last hope and refuge. Yet natural disasters such as earthquakes frequently and mercilessly destroy these vital public buildings, leading to a secondary collapse of both lives and hope. Therefore, ensuring these structures remain standing amidst violent tremors is not merely an engineering problem, but a profound issue concerning social resilience and moral responsibility. Traditional seismic design approaches are no longer sufficient to address increasingly complex challenges; we must adopt new perspectives and systematic solutions to build a stronger line of defense for human life.
Traditional seismic design often focuses on the “hard resistance” of a building’s primary structure—that is, resisting seismic forces by enhancing the strength and stiffness of beams, columns, and walls. While this approach is certainly important, for facilities with specialized functions and high occupancy rates, such as hospitals and schools, merely ensuring that the building does not collapse is far from sufficient. We must transcend the baseline mindset of mere “survival” and shift toward the higher-order goal of “functional sustainability.” This means that after an earthquake, buildings must not only remain standing, but their internal medical equipment must function normally, operating rooms must maintain sterile environments, classrooms must be able to resume teaching quickly, and evacuation routes must remain absolutely unobstructed. This paradigm shift from “structural safety” to “functional preservation” is precisely the core of the new approach to seismic design.
Achieving this goal requires multidimensional, interdisciplinary collaborative innovation. In terms of structural systems, in addition to applying mature technologies such as base isolation and energy-dissipating damping, the “functional modularization” of the entire building or its critical components is emerging as a trend. For example, core surgical areas and intensive care units in hospitals, or load-bearing walls and stairwells in schools, can be designed as independent “safety islands” or “resilient units” with higher seismic resistance ratings. Even if other parts of the building are damaged, these core units remain intact, serving as “lifesaving strongholds” that can be put into immediate use after a disaster. At the same time, the use of deformable, recoverable resilient materials and components allows buildings to undergo non-destructive deformation within a certain range and absorb energy. After an earthquake, they can quickly resume functionality through simple repairs, which is more economical and practical than pursuing “complete rigidity.”
The seismic safety of equipment must not be overlooked either. Expensive MRI and CT scanners in hospitals, as well as laboratory equipment, bookshelves, and suspended ceilings in schools, can easily become sources of secondary injury during an earthquake. Next-generation solutions emphasize “system anchoring” and “intelligent response.” By dynamically coupling critical equipment to the building structure through pre-embedded anchoring systems, flexible connectors, and dampers, the risk of swaying and overturning is significantly reduced. Furthermore, IoT sensors and automated control systems can be integrated. When an earthquake warning is issued, the system can automatically lock the doors of precision equipment cabinets, cut off non-essential power supplies, and activate emergency lighting, buying valuable time for personnel evacuation and asset protection.
A building’s seismic resilience cannot be achieved without considering non-structural elements. These include indoor and outdoor piping systems, exterior wall finishes, glass curtain walls, and the external environment. Pipe ruptures can lead to flooding or fires in hospitals, while exterior wall detachment can block rescue routes. Therefore, under this new approach, water supply and drainage, electrical, and ventilation ducts should employ flexible connections and allow for deformation; curtain walls and cladding materials must possess sufficient deformation adaptability; open spaces such as school playgrounds and hospital courtyards should be pre-planned as safe emergency shelters and supply distribution points, with their access routes and ground bearing capacity incorporated into the overall seismic design.
Finally, and most crucially, is the human factor. Even the most advanced technology requires human cognition and action to be effective. Therefore, a new approach to seismic design must incorporate the “human factor.” This means that during the design phase, evacuation and rescue routes for people (including patients, students, medical staff, and teachers) must be thoroughly simulated to ensure that pathways remain accessible even under extreme conditions. Regular, targeted earthquake drills should be organized, and key seismic safety facilities and designated safe zones should be integrated into the building’s daily wayfinding system, making safety awareness an integral part of spatial memory. Schools should further integrate knowledge of building seismic resistance into science education, cultivating risk awareness and response capabilities in the next generation from an early age.
In summary, ensuring that hospitals and schools remain standing during disasters is no longer merely a matter of pursuing structural robustness; rather, it is a systematic social engineering endeavor that integrates structural engineering, mechanical and electrical engineering, materials science, information technology, and even behavioral psychology. It requires us to shift from passive disaster defense to active resilience-building; from a singular engineering perspective to a holistic approach that embraces life, function, and culture. Only by adopting and implementing these new paradigms of seismic design can we truly infuse society’s most vulnerable links with indomitable strength, ensuring that these places—which bear the weight of life and the future—remain reliable, steadfast havens amidst any storm or upheaval.
