Live Load refers to the temporary or movable weight that a building or structure must support, beyond its own weight. Think of it as the weight of people, furniture, vehicles, or equipment that can move in and out of a building or across a bridge. Civil engineers need to calculate and plan for these changing weights to ensure structures are safe. This is different from "dead load" which is the permanent weight of the building itself. When reviewing resumes, you'll often see this term in context of structural design and analysis work.
Calculated Live Load requirements for multi-story commercial buildings

Q: How do you approach optimizing structural designs while ensuring they meet live load requirements?
Expected Answer: A senior engineer should discuss balancing cost-effectiveness with safety margins, mention building codes, and explain how they consider different usage scenarios to determine appropriate live load values.
Q: Can you explain how you would handle a situation where actual live loads exceed the original design specifications?
Expected Answer: Should discuss assessment procedures, safety implications, potential reinforcement solutions, and the importance of clear communication with stakeholders about load limitations.
Q: What factors do you consider when calculating live loads for different types of buildings?
Expected Answer: Should mention building usage (office, residential, warehouse), local building codes, and how occupancy patterns affect load calculations.
Q: How do you determine appropriate safety factors for live load calculations?
Expected Answer: Should explain basic principles of safety margins, standard practices, and how different building uses require different safety factors.
Q: What is the difference between live load and dead load?
Expected Answer: Should explain that live loads are temporary/movable weights (people, furniture, vehicles) while dead loads are permanent weights (building structure itself).
Q: What are some common sources of live loads in buildings?
Expected Answer: Should list examples like occupants, furniture, vehicles, equipment, and explain how these vary by building type.
