The primary types of loads that affect bridges include dead loads, live loads, wind loads, and seismic loads.

Dead loads refer to the permanent static weight of the bridge structure itself, including elements such as beams, decks, and other components that do not change over time. Live loads account for the variable loads from vehicles, pedestrians, and other temporary influences that can change based on usage and environmental conditions.

Wind loads are crucial for bridge design, especially for tall or exposed structures. They represent the forces exerted by wind on the bridge, which can induce vibrations and require careful consideration in the design to ensure stability and safety.

Seismic loads come into play in areas prone to earthquakes. These loads account for the forces generated during seismic events and impact how the bridge withstands ground motion, ensuring it remains safe for use during and after such incidents.

This comprehensive approach to understanding the loads allows for a better design that can withstand various scenarios, making option C the most accurate representation of the types of loads influencing bridge design and analysis.
