What type of forces do structural components typically support?

Structural components are designed to support a combination of both non-variable and variable forces. Non-variable forces, also known as dead loads, remain constant over time. These can include the weight of the structure itself, such as beams, walls, roofs, and any permanent fixtures. On the other hand, variable forces, or live loads, can change over time and include occupants, furniture, equipment, snow, wind, and seismic forces.

By understanding that both types of forces are acting on structural components, one can appreciate how critical engineering principles and material strengths are utilized to ensure safety and stability in construction. Designing structures to withstand these varying forces is essential to prevent failure and maintain the structural integrity of buildings.
