When a major earthquake strikes, how do our schools and hospitals remain standing?

When the shadow of disaster looms over the land, earthquakes test the fragile defenses of human society with their unpredictable fury. In those life-or-death moments, two types of buildings bear a weight far greater than mere bricks and rubble—schools and hospitals. They are not merely physical spaces, but beacons of hope and life. Therefore, exploring how these public buildings can stand firm amidst the earth’s tremors is not only a matter of engineering technology, but also a solemn commitment to the dignity of life and the continuity of civilization.

Public buildings, especially schools and hospitals, must adhere to seismic design standards far stricter than those for ordinary residential structures due to their high occupancy, critical functions, and the presence of vulnerable individuals (such as students and patients) and vital equipment. This is not merely a matter of being “stronger,” but rather a comprehensive “resilience” solution that spans from concept to detail. At its core lies the principle of “standing firm in major earthquakes, being repairable after moderate earthquakes, and remaining undamaged in minor earthquakes,” ensuring that the building’s main structure does not suffer catastrophic collapse during extreme seismic events, thereby securing precious “golden time” for evacuation and emergency response.

Achieving this goal begins with scientific site selection and exceptional design. Avoiding high-risk areas such as active fault zones, landslides, and liquefaction zones is a prerequisite. In the design phase, modern seismic concepts have evolved from merely resisting seismic forces to a “ductile design” that employs “flexibility to overcome rigidity.” Engineers utilize advanced technologies such as base isolation and energy-dissipating systems. For example, installing seismic isolation bearings between the building’s base and the foundation is akin to putting “skates” on the structure. This effectively isolates and dissipates most of the seismic energy transmitted from the ground, allowing the upper structure to “glide” smoothly. Meanwhile, installing dampers at critical points within the building is like equipping it with “shock absorbers,” which convert seismic kinetic energy into heat, significantly reducing structural deformation. The application of these technologies in hospital operating rooms, intensive care units, and school buildings maximizes the safety of occupants and protects sensitive equipment.

The selection of building materials and construction quality are critical factors in turning seismic design plans into reality. The use of high-strength steel, high-performance concrete, and fiber-reinforced composite materials enhances the load-bearing capacity and deformation resistance of structural components. However, even the most advanced designs rely on meticulous construction to be realized. From the density of rebar tying and concrete pouring and curing to the precise implementation of various seismic structural measures, every step of the process affects the final safety performance. Strict third-party supervision and a comprehensive quality traceability system are essential safeguards against substandard construction and ensure the structural “skeleton” of a building remains robust.

For schools and hospitals, a sturdy “shell” alone is far from sufficient. The safety of non-structural components is equally critical. This includes interior and exterior wall plastering, suspended ceilings, lighting fixtures, large storage cabinets, medical equipment, laboratory instruments, and exterior wall decorations. During an earthquake, the detachment, toppling, or damage of these components is often the primary cause of casualties, blocked passageways, and functional paralysis. Therefore, systematic seismic retrofitting or flexible connections must be implemented. For example, filing cabinets and large medical equipment should be securely anchored to walls or floors, and lightweight, flexible ceiling systems should be used to ensure the absolute safety of components along evacuation routes.

A comprehensive seismic solution must also include routine emergency preparedness and the cultivation of a culture of resilience. Schools should regularly conduct earthquake evacuation drills tailored to students’ cognitive development and integrate emergency knowledge into the curriculum. Hospitals, meanwhile, must develop detailed disaster response plans covering patient transfer, emergency power supply, procedures for interrupted surgeries, management of medications and medical equipment, and rapid post-disaster functional recovery. Clear emergency signage within buildings, easily accessible evacuation doors, and backup emergency lighting and communication systems are all vital components of the lifeline network.

Globally, as evidenced by practices in seismically active countries such as Japan and New Zealand, prioritizing the reinforcement and high-standard protection of schools and hospitals has become a social consensus and a policy priority. This represents an investment in the future, prioritizes the protection of society’s most vulnerable groups, and reflects a society’s level of civilization and sense of responsibility. Every investment in the seismic safety of public buildings strengthens our shared future.

When the tremors of a major earthquake subside, the sound of students reading from school buildings that remain standing and the hope for life sustained within fully functional hospitals will be the highest reward for all our efforts. Making schools the safest havens and hospitals the most reliable bastions of life requires the sustained attention and action of the government, engineers, builders, administrators, and indeed every citizen. Only in this way can we safeguard the core values of civilization and the boundless potential of life in the face of nature’s unpredictability.
