Dead loads are best described as full-time permanent loads.

• A. Sometimes
• B. Not defined
• C. False
• D. True

Answer: (D)

Dead loads are fixed, permanent weights that act on a bridge at all times. This includes the self-weight of the structure—like the deck, girders, and foundations—as well as any permanently attached equipment or fixtures. These loads remain essentially constant over the life of the bridge, not varying with traffic or usage. Because they are present continuously, they are treated as full-time loads in design, inspection, and load-rating calculations. In contrast, live loads come from traffic and usage and can change, while environmental effects like wind or temperature are separate categories with their own characteristics. So describing dead loads as full-time permanent loads is exactly how engineers categorize them. Describing them as sometimes, not defined, or false would not fit their constant, enduring nature.
