What is the purpose of seismic design criteria in building codes?

The purpose of seismic design criteria in building codes is fundamentally to ensure that structures are capable of withstanding the stresses and forces generated during an earthquake. This involves the application of specific material and design specifications that take into account the potential ground motion and seismic activity of a given area. These criteria are based on extensive research and data from past earthquakes, which inform the engineering practices meant to enhance the resilience of buildings, ensuring they remain safe and functional during seismic events.

The selected criteria guide architects and engineers in the design process, promoting the use of suitable materials and structural designs that can absorb and dissipate seismic energy. This proactive approach not only protects the integrity of the structure but also prioritizes the safety of the occupants and the surrounding community, ultimately reducing the risk of collapse and associated injuries in the event of an earthquake.

In contrast, enhancing aesthetic appeal, reducing construction costs, or establishing building maintenance guidelines are important aspects of construction and architecture but do not directly address the critical need for safety and stability in seismic-prone areas.
