Which term means any action that maintains or alters the building or its components?

• A. Building Construction
• B. Compression
• C. Force
• D. Tension

Answer: (C)

In structural terms, force is the broadest description of anything that pushes, pulls, or twists on a building or its components. Any action that can affect the structure—gravity pulling on it, wind pressing on surfaces, earthquakes shaking it, or internal reactions within members—falls under force. These forces can keep the building in balance (static equilibrium) or cause deformation and changes in the components. That makes force the best answer because it encompasses all such actions. Compression and tension are specific kinds of forces (a pushing effect and a pulling effect, respectively), while building construction refers to the process of putting the structure together, not the actions acting on it.
