Commercial Building Inspector B2Floor ConstructionMedium
A commercial building inspector is reviewing the structural plans for a new single-story commercial retail building with a large open sales floor. The floor system is specified to be a reinforced concrete slab-on-grade. What is the minimum uniformly distributed live load required for the sales floor area of a retail store, according to the IBC?
- A100 psf
- B50 psf
- C75 psf
- D40 psf
Show answer & explanationAnswer & explanation
Correct answer: A. 100 psf
According to IBC Table 1607.1, 'Minimum Uniformly Distributed Live Loads, L0, and Minimum Concentrated Live Loads,' for retail sales floors (first floor and basement), the minimum uniformly distributed live load is 100 psf (4.79 kN/m2).
Why the other options are wrong
- B. 50 psf is for certain light storage or light manufacturing areas, or upper floors of offices, not general retail sales.
- C. 75 psf is for heavy manufacturing or some storage areas, but not the general minimum for retail sales floors.
- D. 40 psf is typically for office areas or residential occupancy, not retail sales.
Retail Sales Floor Live Load
The minimum uniformly distributed live load required by the IBC for the design of floor systems in retail sales areas.
- Found in IBC Table 1607.1.
- Accounts for occupants, merchandise, and movable fixtures.
- Critical for structural design and safety.
Memory trick: Retail floors need 100 pounds of strength for shoppers and wares.
