Define the term "structural integrity" as it pertains to building safety.

The term "structural integrity" relates directly to a building's capacity to support the loads it is designed to bear without experiencing failure or collapse. This encompasses not only the weight of the building materials themselves but also additional loads such as occupancy, furniture, snow, wind, and seismic activity. Achieving structural integrity ensures the safety of occupants and maintains the building's functionality over time.

Considering the other options, while aesthetic appeal, accessibility, and energy consumption are all important factors in building design and functionality, they do not directly relate to the concept of structural integrity. A building could be visually appealing, easy to navigate, or energy-efficient, yet still lack the necessary strength and durability to be considered safe. Therefore, understanding and ensuring structural integrity is critical for compliance with building codes and the overall safety of the structure.
