In structural assessments, a load that does not vary over time is called what?

• A. Static loading
• B. Dynamic load
• C. Variable load
• D. Cyclic load

Answer: (A)

Loads that do not vary over time are called static loads. In structural assessments, treating a load as static means its magnitude, direction, and point of application stay constant, so you can analyze the structure using simple static equilibrium without worrying about inertia or time-dependent effects. Dynamic loads, by contrast, vary with time and can induce vibrations and transient responses. A variable load changes over time but not necessarily in a repeating pattern, while a cyclic load repeats in a regular cycle. So the load that remains constant over time is static loading.
