The seismic design of buildings primarily focuses on protecting occupants in the event of an earthquake, but it also has a few important sustainable benefits.
Seismic design plays a vital role in safeguarding structures during earthquakes. While much attention is typically given to the structural elements of a building, it is crucial not to overlook the significance of seismic design for non-structural elements.
In the world of structural engineering, sustainable seismic design (SSD) is a relatively new field of study. In conventional earthquake-resistant systems, attention is focused on the response of the structure to seismic demand, but in SSD, the post-earthquake attributes of the system are as important as those during the event.
Here are four sustainable benefits of the seismic design of non-structural components:
1. Enhanced safety and occupant well-being
Sustainable construction is about more than the environmental impact of the building industry; it is also about the social impact on society and individual lives.
Because seismic design prioritises the safety of occupants and protects human life, it inherently contributes to the sustainability of a building.
2. Preservation of critical functions
Seismic design further supports social sustainability by reducing the economic and social impact in the aftermath of a disaster.
Seismic design of ceilings can protect important systems from damage, particularly in critical infrastructure buildings such as hospitals, schools, and government facilities, allowing the community to be safer and more resilient during the recovery period.
3. Reduced environmental impact
By incorporating seismic design principles, buildings can be more resilient, leading to a reduced demand for new materials and a decreased carbon footprint during reconstruction. This not only conserves natural resources but also helps mitigate the greenhouse gas emissions associated with the manufacturing and transportation of building materials.
4. Longevity and durability
Buildings that incorporate seismic design principles during construction are likely to exhibit increased longevity and durability. This can result in reduced maintenance requirements, further minimising resource consumption and waste generation over the life cycle of the structure.
