What thickness of concrete will it take to hold up a 100x 25 mezzanine with live load of 60lbs per square foot?

To determine the required thickness of concrete for a mezzanine with a live load of 60 lbs per square foot, factors such as the span of the concrete slab, reinforcement, and design codes must be considered. Generally, a concrete slab for such applications is commonly designed to be at least 4 to 6 inches thick, depending on the specifics of the load and reinforcement strategy. Consulting with a structural engineer is essential for precise calculations and to ensure compliance with local building codes.
