What aspect does a structural system primarily support?

A structural system primarily supports the pull of gravity, which is a fundamental aspect of architectural design. Gravity is the force that pulls objects toward the earth, and any structure must effectively manage this force to ensure stability and safety. In essence, the structural elements—such as beams, columns, and foundations—are designed to withstand loads that result from gravity, including the weight of the building materials, occupants, and any additional loads such as furniture or equipment.

The capability to support gravity is critical for the integrity of a structure, as failure to adequately address these forces can lead to structural failure. While other factors such as wind resistance, thermal expansion, and aesthetic balance play important roles in the overall design and function of a building, the primary responsibility of the structural system is to ensure that it remains stable and secure under the influence of gravity.
