Ice pressure on a bridge is categorized as which load type?

• A. Primary Live Load
• B. Dead Load
• C. Secondary Live Load
• D. Fatigue

Answer: (C)

The main idea is how loads on a bridge are classified. Ice pressure is a variable, weather-driven external force that isn’t part of the structure’s permanent weight and isn’t the standard traffic the bridge is designed to carry. The usual traffic load represents the primary live load. Ice pressure adds on top of that under certain conditions, so it’s treated as a secondary live load. It isn’t a dead load, which would be the fixed weight of the bridge itself, and it isn’t fatigue, which refers to a failure mechanism from repeated loading rather than a distinct load category.
