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

The purpose of seismic design criteria in building codes is to ensure that structures can withstand the forces and movements associated with earthquakes. These criteria set forth specific material and design specifications that help enhance the structural integrity and resilience of buildings during seismic events. By adhering to these guidelines, architects and engineers can create designs that minimize the risk of structural failure, protect the lives of occupants, and reduce the potential for property damage during an earthquake.

This focus on safety and performance under seismic loading reflects the understanding of how energy is released during an earthquake and the impact it has on various types of buildings and infrastructure. A well-designed structure following seismic design criteria can effectively dissipate seismic forces, allowing it to maintain stability and functionality even in the face of natural disasters.

The other options do not directly relate to the primary goal of seismic design criteria. While aesthetics, cost reduction, and maintenance are important considerations in construction and building management, they are not the fundamental intent of the seismic criteria which centers solely on earthquake resistance and safety.
