"Live Load" refers to the weight of movable objects that a structure must support, such as people, furniture, vehicles, and equipment. Unlike permanent loads, which are constant and fixed, live loads can change over time, making them crucial for engineers to consider when designing buildings, bridges, and other structures. In engineering, live loads are typically calculated based on expected usage and safety standards. For example, the American Society of Civil Engineers provides guidelines to help determine appropriate live load values for different types of structures, ensuring they can safely accommodate varying conditions and activities.
